What are some cows milk/formula feeding risks?
over dilution or under dilution of formula
sterile water for milk formula
nursing bottle syndrome
inappropriate milk substitues (soy beverages, goats milk)
What risks are associated with under dilution?
caloric dense formula
exessive protein and solute
increased risk of dehydration, metabolic acidosis, and hypernatremia (high Na and solute load)

possible hot spots that can cause severe burns to infants
What should be done to prevent nursing bottle syndrome?
avoid nocturnal and long term used of bottles containing fluids other than water
do not dip pacifiers or nipples in sugar or honey --> leads to severe dental carries
Why is goats milk an inappropriate milk substitute?
deficient folic acid, vit B6 and B12
higher in protein (3.6g/100mL) vs human milk (1g/100mL) and formula (1.4 g/100 mL) --> risk of dehydration and higher renal solute load
low Ca:P -> risk of hyperphosphatemic tendency (painful and prolonged contraction) in small immature infants
Why are plant based beverages (soy milk, rice based beverages) inappropriate milk substitutes?
low energy density <80% energy density of infant formulas - malnutrition if SB/RB are sole source of nutrition
failure to thrive
insufficient vit D -> rickets, hypocalcemia
several (but nol all) products bear label statements that the product is not a substitute for infant formula
Mn content of these products -> risk of neurotoxicity (infants uniquely sensitive); Mn exposure associated with long term effects on learning ability until after 1 year of age
phosphate compounds, particularly phytic acid (phytate, hexaphosphoinositol) -> decrease the bioavailability of some nutrients

the infants weight has doubled
consumes >32 Fl. oz daily of formula and is still hungry
consumes 8 Fl. oz and is still hungry <4 hours later
sits with support, controls head movments
What does Beikost mean?
introduction of solid foods in addition to breast milk and infant formula
What are the risks of introducing weaning too early?
increased morbidity due to diarrhea and food allergies
under-nutriton due to the normal decrease in maternal milk production as the infant is withdrawn from the breast
may increase the risk for allergies and maybe diabetes
increased risk of choking
rejection of food leading to adverse relationship b/w child and caregiver
What are the risks of introducing solid food too late?
decreased immune protection
under nutrition when exclusive breast feeding or formula feeding becomes inadequate
inadequate energy and protein intake and deficiencies of Fe, Zn, vit A and vit D

What development occurs at 3-6 months?
At ___ months infant can move head forward and turn head away if full or disinterested
At what ages does a greater need for additional protein and Fe coincide with more mature chewing patterns?
What is rotary chewing and when does it develop?
lateral jaw movements
usually at 8 months when infant develops pairs of opposing teeth
6-8 months is a critical period of development in relation to eating. What does it require?
requires more specific stimulus of introduction of solid food
otherwise it is more difficult accepting foods later, increased risk of nutrient deficiencies (Fe)
child increasingly reluctant to try new tastes; manipulative behavior
1-3 years the child is still developing __________________________ increasing its ability to eat
orally and muscularly
at what age can the infant hold the bottle by itself
what foods should be added to the diet of a 4-6 month old child
iron fortified rice cereal, followed by other single-grain cereals, mixed with breast milk, formula, or water
perhaps vegetables before fruits so the baby will learn to like their less sweet flavors
what foods should be added to the diet of a 6-8 month old child
infant breads and crackers
mashed vegetables and fruits, and their juices
if energy and protein requirements are met then _____________________________ deficiencies are unlikely.
vitamin, mineral and trace element

What is methemoglobinemia?
impairs oxygen binding
How do you test for allergies?
What allergies account for 75% of all allergies?
wait 3 days after the introduction of new foods to check for allergic symptoms
cow's milk, egg whites, peanuts
What reduces the risk of allergies?
exclusive breast feeding in the first 6 months
why should the use of fruit juices be limited?
excessive intake of sorbitol is harmful to infants
dont feed before 6 months
grape juice is preferable as orange can cause allergies and apple and pear have too much sorbitol
juice given in a bottle can lead to dental carries
What is sorbitol? and why is it harmful to babies?
sorbitol is a reduced alcohol derivative of glucose (in fruit juices eg apple, peach, pear,and plum)
sorbitol proceeds unchanged to the colon-> osmotic effect -> fluid enters the colon -> diarrhea
What is infant colic associated with?
associated with CHO malabsorption from fruit juices containing sorbitol and a high fructose:glucose ratio
malabsorbed CHO produces excess hydrogen gas
increase in breath hydrogen gas excretion levels

more fiber from complex CHO
increased fiber intake + Lower animal protein ---> decreased essential mineral bioavailability (phytates and oxalates)
linear growth affected by Zn deficiencies cause by higher intake of plant foods

normal head circumference, lower weight and greatly lowered height
-normally malnutrition related including poverty or infant behavioral problems
-also macrobiotics (insufficient vit D [higher incidence of rickets], calories, protein, Fe, and riboflavin intake)
