Breastfeeding Flashcards
Fat changes through the breastfeeding session from ___ to __
Fore milk (less fat) - hindmilk (more fat)
What can fat free formula lead to
Linoleic acid deficiency and malnutrition
What is HMO (what macronutrients)
Human milk oligos: strengthens good gut bacteria
Carbs
Describe milk flow
Milk flows from alveolar cells where it’s produced by the lactiferous sinuses = fore milk
More suckling = oxy released, let down reflex occurs
More fat injected becomes hind milk
Hormones: Estrogen
Stimulates growth and specification of ducts - preps for milk production
Levels drop after birth and remain low for several months of breast feeding
Hormones: progesterone
Low levels after birth –> stimulate prolactin production
Growth in alveoli and lobes ***
Hormones: prolactin
When is response highest
Suckling stimulates anterior pituitary to release
Acts on Acinar cells to produce milk
2-6am
Hormones: oxytocin
Suckling stimulates release from posterior pituitary
Contracts myopic helical cells around alveoli
Does oxy act only one breast
No acts on two breasts
Early and mid hunger cues
Early - rooting, mouth opening and licking
Mid - hands to mouth, cooing, sucking sounds
Rate of sucking
1 suck per second with let down
2 sucks per second when milk flow slows (near end)
Ratio of whey and casein in breastmilk and cows milk
60:40 in breast milk and 20:80 in cows milk
