Growth Assessment
WHO Growth Charts
Gold standard for children 0–5 years; UK-WHO charts used in UK/GCC for all ages.
| Measurement | Tool | Normal Z-score |
|---|---|---|
| Weight | Calibrated scales | -2 to +2 SD |
| Length/Height | Stadiometer / recumbent board | -2 to +2 SD |
| Head Circumference | Non-stretch tape (OFC) | -2 to +2 SD |
| BMI-for-age | Weight(kg)/Ht(m)² | 2nd–91st centile |
| MUAC | MUAC tape mid upper arm | ≥12.5 cm ≥6m |
Z-score below -2 = underweight/stunted/wasted. Z-score below -3 = severe acute malnutrition.
Centile Plotting — Key Technique
- Corrected age: Subtract weeks of prematurity from chronological age — mandatory until 2 years corrected for preterm infants (<37 weeks)
- Serial plotting: Single measurement is a snapshot — trends over time are diagnostic
- Crossing centiles: Crossing 2+ centile lines downward is clinically significant
- Measurement accuracy: Remove shoes/heavy clothing; use same scales; repeat if in doubt
- Weight gain benchmarks: 0–3 m: ~200 g/week; 3–6 m: ~150 g/week; 6–12 m: ~100 g/week
- Head growth: OFC rises ~1 cm/week in first 12 weeks — monitor for macro/microcephaly
Failure to Thrive (FTT)
Diagnostic Criteria
- Weight-for-age <2nd centile
- Weight crossing 2+ centile lines downward
- Weight consistently below expected for height
Assessment Tools
- Full feeding history (frequency/volume/type)
- Stool pattern (consistency/frequency/blood)
- 3-day food diary (weighed/estimated)
- Observation of feeding (latch/bottle technique)
- Social history (poverty/neglect risk factors)
Organic Causes
- Cardiac: congenital heart disease (increased energy expenditure)
- GI: malabsorption, coeliac, IBD, reflux
- Renal: CKD, renal tubular acidosis
- Endocrine: hypothyroidism, GH deficiency
- Respiratory: CF, chronic lung disease
Non-Organic Causes
- Feeding difficulties / aversions
- Neglect or emotional deprivation
- Poverty / food insecurity
- Parental anxiety → restrictive feeding

Common Breastfeeding Problems
| Problem | Signs | Management |
|---|---|---|
| Engorgement | Firm/hot/painful breasts | Feed frequently, warm compress, express to comfort |
| Mastitis | Fever, localised red hard area | Continue feeding, flucloxacillin if not resolving in 24h |
| Inverted nipple | Flat/inverted nipple | Nipple shields, breast shells, pump to draw out |
| Tongue-tie (ankyloglossia) | Poor latch, clicking, slow gain | IBCLC assessment, frenotomy if symptomatic |
| Low supply (perceived) | Maternal anxiety | Feed-on-demand, skin-to-skin, reassure |
BFHI Ten Steps: Baby Friendly Hospital Initiative — skin-to-skin, rooming-in, no formula supplementation unless medically indicated, support for breastfeeding on discharge.
Formula Feeding
Formula Types
- First infant formula: Cow's milk whey-dominant — suitable from birth to 12 months
- Hydrolysed formula (eHF): CMA, mild–moderate — e.g. Aptamil Pepti
- Amino acid formula (AAF): Severe CMA / FPIES — e.g. Neocate, Nutramigen AA
- Soya formula: Not recommended under 6 months (phytoestrogens)
- Follow-on formula: 6–12 months — NOT necessary
Safe Preparation (WHO/NHS)
1
Boil fresh water, cool to ≥70°C (kills Cronobacter)
2
Add exact level scoops — do not pack or heap
3
Cool rapidly under running cold water
4
Test on inner wrist — feed immediately; discard after 2 hours
Introduction of Solids
WHO/NHS: Introduce complementary foods at around 6 months. Never before 17 weeks (4 months).
Readiness Signs (all three needed)
- Can sit with support and hold head steady
- Can coordinate eyes, hands and mouth
- Can swallow food (lost tongue-thrust reflex)
Approaches
- Spoon feeding: Smooth purées → mashed → lumpy
- BLW (Baby-Led Weaning): Soft finger foods from 6 months
- Combined: Most families use both approaches
Early Allergen Introduction (6–12 months)
PeanutEggWheatCow's milkSoyaFishShellfishSesameTree nuts
Introduce one new allergen at a time; wait 2–3 days; continue feeding regularly once tolerated (LEAP trial evidence).
Mixed Feeding & Responsive Feeding
Mixed Feeding
- Combining breast and formula is valid choice
- Establish breastfeeding first (4–6 weeks) before introducing bottles
- Use paced/responsive bottle feeding to avoid overfeeding
Responsive Bottle Feeding Principles
- Semi-upright position (not flat)
- Tilt bottle just enough to fill teat
- Allow baby to pace (take breaks)
- Never force the last drop
- Skin-to-skin and eye contact during feeds
- Wind mid-feed and at end
Average formula intake: 150–200 ml/kg/day in first weeks; decreases as solids increase from 6 months.
Special Dietary Requirements
Cow's Milk Allergy (CMA) — NICE NG121
IgE-Mediated (Immediate)
- Onset: within minutes–2 hours
- Urticaria / angioedema
- Vomiting, wheeze, rhinitis
- Anaphylaxis (severe)
- Skin prick test / specific IgE positive
Non-IgE-Mediated (Delayed)
- Onset: hours–days after exposure
- Reflux-like symptoms
- Loose stools / blood in stool
- Eczema flares
- Colic / distress
- SPT/IgE negative — clinical diagnosis
iMAP Management Pathway
1
Breastfed: Maternal exclusion of dairy (± soya) for 2–4 weeks trial; calcium supplement for mother
2
Formula fed (mild–moderate): Extensively hydrolysed formula (eHF) e.g. Aptamil Pepti, Nutramigen
3
Formula fed (severe / not tolerating eHF): Amino acid formula (AAF) e.g. Neocate Syneo, Nutramigen AA
4
Challenge testing: Milk ladder at ~9–12 months under dietitian supervision
Prognosis: Majority (85–90%) outgrow CMA by age 3–5 years. IgE-mediated tends to persist longer.
Nutritional Requirements by Age
| Age | Energy (kcal/kg) | Protein (g/kg) | Fluid (ml/kg) |
|---|---|---|---|
| 0–3 months | 110–120 | 2.1 | 150 |
| 3–6 months | 100–110 | 1.8 | 150 |
| 6–12 months | 95–100 | 1.5 | 120 |
| 1–3 years | 80–90 | 1.1 | 100 |
| 4–6 years | 70–80 | 0.9 | 90 |
| 7–10 years | 60–70 | 0.9 | 70 |
| 11–14 years | 50–60 | 0.85 | 50–60 |
Key Micronutrients in GCC & UK
| Nutrient | Supplement | Indication |
|---|---|---|
| Vitamin D | 400 IU/day drops | All breastfed infants from birth; all infants Oct–Mar in UK |
| Iron | Drops (2 mg/kg/day) | Preterm / low birthweight from 4 weeks; toddlers at risk |
| Vitamin A | 200–400 mcg | Developing world; often low in GCC |
| Iodine | Diet adequate | Monitor in vegan infants/breastfeeding mothers |
Avoid under 2 years: Added salt, added sugar, honey (botulism risk <12m), whole nuts (choking), low-fat products, excessive fruit juice or squash.
FPIES — Food Protein-Induced Enterocolitis Syndrome
- Mechanism: Non-IgE cell-mediated; T-cell mediated GI hypersensitivity
- Onset: Profuse, repetitive vomiting 1–4 hours post-trigger ingestion
- Triggers: Cow's milk, soya, rice, oats, fish (chronic FPIES: ongoing exposure)
- Presentation: Profound lethargy, pallor, dehydration — can mimic sepsis
- Acute management: IV/NG rehydration, ondansetron may abort reaction, avoid trigger
- Diagnosis: Clinical — no reliable biomarkers; OFC under specialist supervision
- Prognosis: Most resolve by 3–5 years; less predictable than CMA
FPIES can present with hypovolaemic shock. Ensure parents have an emergency action plan and know to call emergency services.
Toddler Diarrhoea
Normal variant — reassure parents once other causes excluded.
- Age: 1–5 years, typically 18 months – 3 years
- Features: 3–6 loose/watery stools/day, often undigested food visible
- Causes: Excess fruit juice (sorbitol/fructose), excess squash, high fruit intake, low fat intake
- Growth: Normal weight gain — distinguishes from malabsorption
- Management: Reduce juice (<120 ml/day), ensure adequate fat in diet, avoid low-fat foods
- Red flags requiring investigation: Blood in stool, weight loss, failure to thrive, fever, nocturnal stools
Foods to Avoid in Toddler Diarrhoea
Apple juicePear juiceSquash/cordialExcessive fruitSorbitol sweets
Nutritional Support in Sick Children
PICU/NICU Nutrition — ESPGHAN Guidelines
ESPGHAN Recommendation: Initiate enteral nutrition within 24–48 hours of PICU admission in all haemodynamically stable children.
Enteral Access Selection
| Route | Indication | Key Consideration |
|---|---|---|
| Nasogastric (NGT) | Short-term (<4–6 weeks), functional gut | Confirm position before every feed |
| Nasojejunal (NJT) | Gastroparesis, aspiration risk, pancreatitis | Continuous feeds only; position by imaging |
| Gastrostomy (PEG/RIG) | Long-term feeding (>4–6 weeks) | PEG: endoscopic; RIG: radiological insertion |
| Parenteral (PN) | Non-functional gut, short bowel syndrome | Central line preferred; TPN monitoring essential |
Continuous vs Bolus Feeds
Continuous (pump)
- Better tolerance in critical illness
- Preferred in NJT/post-pyloric
- Flush with water every 4–6h
Bolus/Intermittent
- More physiological (mimics meals)
- Preferred for home feeding, ambulatory
- Gravity or pump-assisted
Refeeding Syndrome
Life-threatening! Occurs in severely malnourished patients on reintroduction of nutrition — rapid electrolyte shifts (especially phosphate).
At-Risk Groups
- Severe acute malnutrition (SAM)
- Anorexia nervosa
- Prolonged fasting / starvation
- Oncology patients post-chemotherapy
- Post-surgical (prolonged ileus)
Monitoring Protocol
| Electrolyte | Frequency | Target |
|---|---|---|
| Phosphate | Daily (first 5–7 days) | >0.8 mmol/L |
| Potassium (K+) | Daily | 3.5–5.0 mmol/L |
| Magnesium (Mg2+) | Daily | 0.7–1.0 mmol/L |
| Thiamine | Give empirically before feeds | Supplement first |
Start at 20–25 kcal/kg/day in high-risk patients; increase slowly over 7–10 days. Do NOT aim for full requirements immediately.
NGT Nursing — Position Confirmation & Safety
Never feed without confirming NGT position!
1
pH testing: Aspirate stomach content — pH ≤5.5 confirms gastric position (use CE-marked pH strips)
2
CXR: Gold standard if pH unreadable; required at initial insertion and if doubt remains
3
Marking: Record external measurement at nostril after each confirmation; check marking matches
4
Document: Record pH, measurement, date/time before every feed or medication
Skin & Nostril Care
- Alternate nostrils when re-siting to prevent pressure injury
- Secure tube with hydrocolloid dressing to prevent nasal trauma
- Inspect nostril skin at each shift — document any redness/ulceration
- Use minimum tape/fixation to maintain skin integrity
Gastrostomy Button Care & Parenteral Nutrition
Gastrostomy Button (PEG/RIG/Balloon Button)
- Lubrication: Water-soluble lubricant (e.g. KY jelly) for button insertion
- Rotation: Rotate button 360° daily to prevent buried bumper syndrome
- Site care: Clean with gauze and saline daily; dry thoroughly
- Granuloma management: Silver nitrate application or topical steroid — per protocol
- Balloon check: Check water volume in balloon weekly (as per manufacturer)
- Accidental removal: Cover stoma with dressing; re-site within 2–4 hours or tract may close
Parenteral Nutrition (TPN) — Key Nursing Points
- Components: Glucose (energy), amino acids (protein), lipid emulsion, electrolytes, vitamins, trace elements
- Line care: Dedicated central line lumen (PICC/CVL); strict aseptic technique
- Monitoring: Blood glucose 4–6 hourly; LFTs weekly; triglycerides, FBC, U&E
- TPN cholestasis: Complication of prolonged PN — bilirubin rises; switch to EN ASAP
- Transition to EN: Begin enteral feeds as gut function returns; wean PN simultaneously
Childhood Obesity Management
Assessment Framework
Clinical Assessment
- BMI centile (UK 1990 charts)
- Waist circumference (waist:height ratio >0.5 = central obesity)
- Blood pressure (hypertension in childhood obesity)
- Fasting glucose (impaired glucose tolerance / T2DM)
- Fasting lipids (dyslipidaemia)
- LFTs / liver USS — NAFLD (fatty liver — increasingly common)
- Sleep history — obstructive sleep apnoea
- Pubertal assessment — early puberty association
- Mental health screen — depression, bullying, self-esteem
HENRY Programme
Health, Exercise, Nutrition for the Really Young
- Evidence-based programme for children under 5 years and families
- 8-week group-based parenting programme
- Focuses on parenting confidence, not just food/activity
- Healthy meals as family, responsive feeding practices
- Emotional wellbeing of parent and child
- Physical activity — active play and reducing screen time
- Delivered by trained health professionals (health visitors/nurses)
MEND Programme
Mind, Exercise, Nutrition, Do it!
- For children 7–13 years with overweight/obesity
- 18-session programme over 9 weeks
- Multidisciplinary: dietitian, physical activity specialist, psychologist
- Mind: Body image, self-esteem, emotional eating
- Exercise: 60+ minutes moderate activity daily
- Nutrition: Traffic light food labelling, portion sizes
- Do it: Family goal-setting and habit formation
Family-Based Behavioural Intervention
Key principle: Whole-family approach — NEVER single out the child. Focus on family health, not individual weight.
Realistic Goals
- Children under 12: Weight maintenance while growing (BMI centile falls naturally)
- Adolescents with severe obesity: Slow weight loss 0.5 kg/month maximum
- Set small achievable goals (SMART goals)
- Focus on behaviours not outcomes (swap TV time for activity)
Motivational Interviewing Principles
- Open questions: "What do you enjoy about being active?"
- Affirm: Acknowledge effort and small successes
- Reflective listening: Reflect ambivalence without judgement
- Summarise: Consolidate change talk at end of consultation
- Avoid confrontation — roll with resistance
- Explore importance and confidence to change (ruler scaling)
Eating disorder risk: Screen at every contact — weight loss interventions can trigger restrictive eating behaviours, especially in adolescent girls. Use EDE-Q or equivalent if concerned.
Pharmacotherapy & Surgical Options
| Treatment | Age/Criteria | Notes |
|---|---|---|
| Orlistat | >12 years, obesity + comorbidities | Lipase inhibitor; GI side effects; fat-soluble vitamin monitoring |
| Semaglutide (Ozempic/Wegovy) | ≥12 years, BMI ≥95th centile + comorbidity (NICE TA) | GLP-1 agonist; weekly injection; nausea common; caution eating disorders |
| Metformin | T2DM or insulin resistance | Off-label for obesity; reduces insulin resistance |
| Bariatric surgery | Adolescents, very limited | Specialist centre only; BMI ≥40 or ≥35 with severe comorbidity; skeletal maturity required |
Important: Pharmacotherapy and surgery are adjuncts — lifestyle intervention must continue alongside. Multidisciplinary team essential including CAMHS for psychological support.
Contraindications & Cautions
- Active eating disorder — absolute contraindication to weight loss drugs
- Pregnancy / risk of pregnancy — semaglutide contraindicated
- Pancreatitis history — GLP-1 agonists with caution
GCC Context & Exam Preparation
GCC-Specific Nutritional Issues
| Issue | GCC Context | Nursing Action |
|---|---|---|
| Childhood obesity | Kuwait, Qatar, UAE among highest rates globally | Early identification, family-based intervention, culturally sensitive approach |
| Early solids introduction | Cultural practice: solids at 4 months (against WHO 6-month guideline) | Educate families — readiness signs, choking risk, gut immaturity |
| Traditional complementary foods | Rice water, dates, honey before 12 months | Honey: botulism risk under 12 months — educate firmly |
| Overfeeding | Fatness associated with health in some Gulf cultures — pressure to overfeed | Normalise growth charts; dispel fat=healthy myth; reassure parents |
| Low exclusive BF rates | Formula marketing, early return to work, cultural norms | Support breastfeeding initiation, BFHI promotion, peer support |
| Vitamin D deficiency | Near-universal in GCC infants — indoor lifestyle, clothing (sun avoidance), dark skin, sunscreen use | 400 IU Vit D daily from birth for all breastfed infants; supplement all under 5 |
