Principles of Infant Feeding Energy Requirements: kcal/kg/d • 0-12 mo: 100-120 • 1-3 yr: 90-100 • 4-6 yr: 80-90 • 7-10 yr: 70-75 • 15+ yr: 45-50
Principles of Infant Feedings Formula fed infants feed every 3-4 hrs. Feedings/day 0-3 Months: 6-8 4-6 Months: 5-7 6-8 Months: 4-6 9-12 Months: 3-5
Principles of Infant Feeding Average Volume of Milk per Feeding • 1st wk: 1-2 oz • 2-4 wks: 2-3 oz • 1-2 mo: 4-5 oz • 3-4 mo: 5-6 oz • 5-6 mo : 7-8 oz • By 12 mo of age, the average child should be taking an average of 24 oz/d.
Infant Formula Indications As substitute for human milk in infants for whom BF is medically contraindicated. As supplement for BF infants who do not gain weight adequately. As a substitute or supplement for human milk whose mother chooses not to BF or not to do it exclusively.
Question • Which of the following statements about infant nutrition is true? • Human milk contains more casein than infant formulas. • Infants who receive increased whey protein have been shown to grow better than those who receive primarily casein. • Iron is absorbed better from cow milk formulas than from human milk. • Lactose-free formulas result in decreased absorption of calcium. • There are no apparent negative effects from the addition of DHA and ARA to formulas.
Benefits of Whey Protein Promotes more rapid gastric emptying. Consists of soluble proteins that are easily digested. Lines the GI tract and plays a role in host defense.
Question • Is iron supplementation required at birth? • No • When should you start iron supplementation? • All babies (including breastfed) should receive supplementation in their food (iron-fortified cereal) by 6 months of age. • In FT infants, iron stores become depleted by 4-6 months of age.
Dietary Recommendations IRON Pre-term: 2 mg/kg/d at 1-12 mo Full-term: 1 mg/kg/d at 4-6 mo Iron Fortified Formula: 12 mg/L Cow’s milk has 0.5mg/L of iron.
Dietary Recommendations VITAMIN D • 400 IU/d Who should receive Vitamin D? • All BF infants, unless they are weaned to at least 1000 ml/d (33 oz) of Vit. D fortified formula. • Formula fed infants ingesting ≤ 1000 ml/d of Vit. D fortified formula. • Children/adolescents who get no sun light, ≤ 1 L of Vit. D fortified milk, no MVI.
