Infant Nutrition: Birth - 6mo
Human milk (preferred)
28
Human Milk
Most desired, complete diet for up to 6mo Provides immunity to the infant (during last 3 months of pregnancy antibodies are provided to baby via passive immunity through the placenta-- lasting a few weeks to months, longer if baby is breastfed) Easily digested >6mo can have significant health impact on children as they grow into adulthood
29
AAP&Nutrition recommends
Exclusively breastfeeding for 6mo Continue for 1yr or longer as complementary foods are introduced Prevents disease into adulthood
30
All infants should receive..
Vit D supplement of 400U/day beginning at hospital discharge
31
After 4 mo exclusively breastfed should receive
Iron supplement of 1mg/kg/day until iron containing foods can be introduced
32
Formula: Milk based
Preferred in full-term infant | Prepared with Cow milk with added veg oils, vitamines, minerals and iron
33
Formula: Soy based
For infants that are lactose intolerant and allergic to milk based formulas or casein protein in cow's milk, or for those parents who wish for a vegetarian diet. Made with soy protein and added veg oils and corn syrup and or sucrose
34
Special formula for Low birth weight infants
Low sodium formula | Predigested protein formula (for those who cannot break down casein or whey)
35
Feedings number/day
In general will decreased from 6 at 1 month to 4-5 at 6 months
36
Total amount of formula ingested/day
32oz
37
Amount of food infant should receive/day
Based on weight, age and if they are taking solid foods Rule of thumb: infants under 6mo who haven't started solid foods should be taking 2-2.5 oz/lb/day Babies eat 3-4oz every 3-4 hr
38

40
Introduce 1st (solid food)

43
Common sequence of introducing foods

44

87
Car Seat recommendations
Children need to be in a rear facing seat until 2yr or until they reach the max height and weight for the seat Once rear facing seat is outgrown: then use forward facing seat Once forward facing seat is outgrown: then need to use a belt positioning booster seat until they have reached 4ft 9in and are between 8-12 yr
