01
Infant Feeding
Breast milk is the gold standard — but safe formula feeding is always an acceptable alternative.
Breastfeeding
- Exclusive breastfeeding recommended for first 6 months (AAP/WHO)
- Feed every 2–3 hours, 8–12 times per day
- Colostrum (first 2–5 days): rich in IgA antibodies, laxative effect (helps pass meconium), concentrated nutrition
- Mature milk by days 10–14 — foremilk (watery, thirst-quenching), hindmilk (fat-rich, satisfying)
- Signs of adequate intake: 6+ wet diapers/day, regains birth weight by 10–14 days, satisfied after feeding
- Breast engorgement: warm compress before feeding (promote letdown), cold compress after (reduce swelling)
- Mastitis: CONTINUE breastfeeding (stopping worsens engorgement). Antibiotics (dicloxacillin).
Formula Feeding
- Standard cow's milk-based formula: 20 calories per ounce
- High-calorie formula (24–27 cal/oz) for failure to thrive or cardiac infants
- Soy-based: for lactose intolerance or milk protein allergy
- Formula must be iron-fortified — prevents iron-deficiency anemia
- Never add extra water (dilutes nutrition and can cause hyponatremia)
- Never prop a bottle — aspiration risk and promotes otitis media
- Prepared formula: use within 24 hours if refrigerated; discard opened can after 48 hours
Cow's Milk — When to Introduce
- Whole cow's milk: NOT until 12 months (immature kidneys can't handle protein load; poor iron source)
- 2% or skim milk: NOT until 2 years (children under 2 need fat for brain development)
- No honey until 12 months (Clostridium botulinum spore risk — infant botulism)
Toddler Milk Risk
Toddlers drinking more than 24 oz (3 cups) of cow's milk per day are at high risk for iron-deficiency anemia — milk fills them up so they don't eat iron-rich foods, and milk interferes with iron absorption. This is one of the most commonly tested pediatric nutrition questions.

02
Introduction of Solid Foods
Timing and food introduction sequence are commonly tested.
When to Start Solids
- Begin at 4–6 months (AAP says around 6 months, earlier is acceptable if ready)
- Signs of readiness: sits with support, good head control, shows interest in food, tongue-thrust reflex diminished
Introduction Sequence and Rules
- Introduce one new food at a time, wait 3–5 days before adding another (to identify allergies)
- First food: iron-fortified single-grain cereal (rice, oatmeal) — mixed with breast milk or formula
- Then: pureed vegetables, fruits, then meats
- No sequence is proven superior — variety is key
- Finger foods (soft, small pieces): around 8–10 months as pincer grasp develops
Serving Size Rule — Toddlers
- 1 tablespoon per year of age per food item (a 2-year-old needs ~2 tbsp of each food)
- Toddlers' appetites are unpredictable — do not force feeding
- Food jags (eating same food repeatedly) are normal in toddlers
Foods to Avoid in Infancy
No honey (<12 months — botulism). No cow's milk (<12 months). No egg whites (<12 months — allergy risk, though current evidence supports earlier introduction for most). No choking hazards: whole grapes, nuts, raw vegetables, popcorn, hard candy. No added salt or sugar.
03
Dehydration Assessment
Children dehydrate faster than adults — GI illness is the most common cause in pediatrics.
- Fontanelmild · mod · severe
- Normal · Sunken · Markedly sunken
- Eyesmild · mod · severe
- Normal · Slightly sunken · Markedly sunken, no tears
- Mucous membranesmild · mod · severe
- Slightly dry · Dry · Parched, cracked
- Skin turgormild · mod · severe
- Normal · Slow recoil (1–2 sec) · Very slow (>2 sec), tenting
- Urine outputmild · mod · severe
- Slightly decreased · Decreased, concentrated · Oliguria or anuria
- Heart ratemild · mod · severe
- Normal to mild increase · Tachycardia · Marked tachycardia
- Blood pressuremild · mod · severe
- Normal · Normal · Hypotension (LATE sign)
Nursing Management
- Mild-moderate: Oral Rehydration Therapy (ORT) — Pedialyte, clear fluids
- Give small amounts frequently: 5 mL every 5 minutes, then increase
- Severe dehydration: IV fluids — NS 20 mL/kg bolus, reassess and repeat as needed
- BRAT diet (bananas, rice, applesauce, toast) — still used clinically but evidence shows returning to normal diet sooner is better
- Do NOT use sports drinks (too much sugar, wrong electrolyte ratio for infants)
Sunken Fontanel
A sunken anterior fontanel in an infant = dehydration. A bulging fontanel = increased intracranial pressure (meningitis, hydrocephalus, ICP). Know both — they are frequently tested in opposite-direction questions.
? An infant has a sunken fontanel, dry mucous membranes, and tachycardia but normal BP. What severity of dehydration does this represent, and what is the priority intervention?
Moderate dehydration (6–9%). Blood pressure is maintained until severe dehydration — its presence is a late sign. Priority: oral rehydration therapy (ORT) with 5 mL every 5 minutes, increasing as tolerated. IV fluids (NS 20 mL/kg bolus) are reserved for severe dehydration or when oral intake fails.
04
Failure to Thrive (FTT)
Weight consistently below the 5th percentile or dropping across two major percentile lines.
Causes
- Organic: underlying disease (CHD, CF, GER, metabolic disorder, malabsorption)
- Non-organic (most common): inadequate caloric intake due to poverty, neglect, improper formula preparation, breastfeeding difficulties, feeding problems
- Mixed: combination of both
Assessment
- Plot weight, height, head circumference on growth chart at every visit
- 24-hour diet recall, feeding observation, parent-child interaction
- Look for signs of neglect: poor hygiene, flat affect in infant, developmental delay
Nursing Interventions
- High-calorie foods and formula — do not restrict fat in children under 2
- Feed in calm, nurturing environment — observe parent-child interaction
- Small frequent meals, allow self-feeding when developmentally appropriate
- Multidisciplinary approach: dietitian, social work, OT, pediatrician
- Report suspected neglect to CPS if non-organic FTT is suspected
05
Iron-Deficiency Anemia (IDA)
Most common nutritional deficiency in children — especially toddlers ages 9–24 months.
Causes in Pediatrics
- Excess cow's milk (>24 oz/day) — fills child up, replaces iron-rich foods, and inhibits iron absorption
- Low dietary iron (picky eaters, vegetarian diets without supplementation)
- Premature infants — depleted iron stores at birth
- Rapid growth periods (infancy, adolescence)
Signs and Symptoms
- Pallor (especially conjunctivae, palms, nail beds), fatigue, weakness
- Pica — craving non-food items (ice, dirt, clay, paper) — classic IDA sign
- Irritability, poor concentration, developmental delays (brain iron-dependent)
- Spoon-shaped nails (koilonychia) in severe/chronic cases
Treatment and Teaching
- Oral iron supplementation — ferrous sulfate between meals on empty stomach (better absorption)
- Give with vitamin C (orange juice) — enhances absorption
- Avoid giving with milk or antacids (decrease absorption)
- Stools will turn dark/black — reassure parents this is normal
- Iron-rich foods: red meat, chicken, fish, lentils, beans, fortified cereals, leafy greens
- Limit cow's milk to 16–24 oz/day for toddlers
- Recheck hemoglobin in 1 month to assess response
Exam Tip
If a question describes a toddler who drinks "a lot of milk" and has pallor and irritability — the answer is iron-deficiency anemia from excess milk intake. The intervention is to reduce milk to 16–24 oz/day, increase iron-rich foods, and supplement with iron. This specific scenario is repeatedly tested on the NCLEX-PN.
06
Toddler & Child Nutrition
Nutritional needs and common feeding concerns by developmental stage.
Toddler (1–3 Years)
- Growth slows significantly — appetite decreases dramatically (normal, not a problem)
- Whole milk until 2 years, then transition to lower fat milk
- Physiologic anorexia — normal decrease in appetite in toddlers. Do NOT force eating.
- Limit juice to 4 oz/day (excess juice = diarrhea, tooth decay, displaces nutrients)
- No added sugar, limit processed foods
School-Age (6–12 Years)
- Steady, predictable growth — appetite increases gradually
- Breakfast is critical for school performance
- High risk for iron deficiency in adolescent females (menstrual loss)
- Calcium needs high for bone density: 1,000 mg/day (age 4–8), 1,300 mg/day (age 9–18)
Adolescent
- Rapid growth = highest caloric and nutrient needs of any age group
- Females: risk for iron deficiency, eating disorders, calcium deficiency
- Males: protein needs for muscle development
- Screen for disordered eating — ask about body image without caregivers present
Obesity Prevention Teaching
Limit screen time to about 1 hr/day for ages 2–5; for older children, set consistent limits with a family media plan (AAP) rather than a fixed number. 60 minutes of physical activity daily. No sugary beverages. Family meals together. Do not use food as reward or punishment.

Frequently Asked Questions
Common student questions on this topic.
Why is breastfeeding recommended over formula feeding?
Breast milk provides passive immunity (IgA antibodies) against many infections, has the ideal nutrient ratio for digestion, lowers the risk of NEC in preemies, reduces allergies, and supports maternal-infant bonding. Mothers benefit from faster postpartum recovery and lower breast/ovarian cancer risk. Exclusively breastfeed for the first 6 months when possible. The only contraindications are maternal HIV (in developed countries), active herpes lesions on the breast, certain medications, and active drug abuse.
When and how should solid foods be introduced?
Start single-grain iron-fortified cereal around 4–6 months, when the infant has good head control and tongue thrust reflex has decreased. Introduce one new food at a time, wait 3–7 days before the next, to monitor for allergic reactions. Order: cereals → vegetables → fruits → meats. Avoid honey before 1 year (botulism risk). Avoid choking hazards (whole nuts, grapes, hot dogs, popcorn). No cow's milk before 12 months.
How do I assess dehydration severity in children?
Children dehydrate faster than adults. Mild (3–5% weight loss): thirst, slightly dry mucous membranes, decreased urine output. Moderate (6–9%): very dry mucous membranes, sunken eyes/fontanel, decreased skin turgor, tachycardia, irritable, capillary refill 2–3 sec. Severe (10%+): lethargy, sunken fontanel, no tears, no urine output, weak pulse, hypotension, mottled skin, prolonged cap refill — medical emergency requiring IV fluids.
What is failure to thrive and what causes it?
Failure to thrive (FTT) = persistently inadequate growth, typically defined as weight below the 5th percentile or crossing two major percentile lines downward. Causes are organic (medical: GERD, malabsorption, CHD, CF, infection) or non-organic (psychosocial: poor feeding technique, neglect, poverty, depression). Assessment includes growth charts, feeding history, family observation, and labs. Multidisciplinary management — pediatrician, dietitian, social work, often hospital admission for monitoring.
How do I calculate maintenance fluids for a child?
Use the 4-2-1 rule (mL/kg/hr) or 100-50-20 rule (mL/kg/24hr): First 10 kg: 4 mL/kg/hr (100 mL/kg/day). Next 10 kg: 2 mL/kg/hr (50 mL/kg/day). Each additional kg: 1 mL/kg/hr (20 mL/kg/day). Example: 24 kg child = (10×4) + (10×2) + (4×1) = 64 mL/hr maintenance. Always double-check pediatric IV calculations against safe dosing range.
What is iron-deficiency anemia in toddlers and how is it prevented?
Iron deficiency anemia peaks at 9–18 months. Cause: switching from iron-fortified formula/breast milk to excess cow's milk (which is low in iron and can cause occult GI bleeding). Signs: pallor, fatigue, pica, irritability, delayed development. Prevention: iron-fortified cereal, limit cow's milk to 16–24 oz/day after age 1, include iron-rich foods. Treatment: oral iron drops, given between meals with vitamin C juice. Stools turn dark; rinse mouth after dosing to prevent tooth staining.
