Class 10: Infant Feeding Flashcards
what is the recommended route for infant nutrition for the 1st 6 months of life?
- exclusive breast/human milk
what supplementations are recommended for infants who are breats/human milk fed
- vitamin D supplementation of 400 IU daily
how can the birther give the infant vitamin D supplementation
- comes in drop form –> put drop on nipple
if infants are weaned off human/breast milk before age 12 months, what should they receive?
- should receive iron-fortified infant formula
what % of people initiate breast/chest feeding? what % continue exclusively for 6 months?
- 90.9% initiate
- 34.4% continue exclusively for 6 months
what factors are associated w breast/chest feeding (3)
- social & economic factors
- marital status
- age of birther
what are examples of social & economic factors that are associated w breast feeding (3)
- food insecurity
- lower income
- lower education
what impact does marital status have on breast feeding?
- single birthers were more likely to stop
what impact does age of the birther have on breast feeding? (2)
- older age = higher chance of breastfeeding for 6 months
- adolescent birthers more likely to stop
what are reasons for stopping breast feeding before 6 months (2)
- inadequate amt of breast milk (rare, assess)
- difficulty w technique
describe the absorption and amt of nutrients in human milk (2)
- nutrients in human milk are more easily absorbed than those informula
- human milk is designed for human infants –> nutritionally superior to any alternative
human milk is considered… why?
- living tissue
- bc it contains almost as many live cells as blood
describe the bacteria in human milk
- bacteriologically safe
due to the differences in absorption of nutrients in human milk, what impact does this have on stools?
- stools will be different on formula
what are benefits of human milk to the newborn? (5)
- immunity
- on demand, safe & fresh w easily absorbed nutrients
- analgesic of NBs
- enhances brain development
- decreases risk of various health conditions
what does human milk reduce the risk of in newborns? (15)
- gastroenteritis
- necrotizing enterocolitis (preterms)
- childhood obesity
- IBD
- celiac
- RSV
- OM
- pneumonia
- UTIs
- bacteremia
- bacterial meningitis
- allergies
- SIDs
- childhood lymphoma
- DM1 and 2
the analgesic benefit of human milk is used for?
- minimally invasive procedures such as venipuncture
what are benefits of chest feeding to the birth (4)
- decreased risk of various health conditions
- helps decrease weight after pregnancy
- help w bonding w infant
- convenient and free
what does human milk reduce the risk of in the birther? (8)
- PPH (helps uterine involution)
- ovarian, uterine, and breast cancers
- RA
- T2DM
- HTN
- hypercholesterolemia
- CVS
- PPD
what should be considered when choosing an infant feeding method (4)
- provide factual info about nutrition & immunological needs met by human milk
- provide info to parents in non-judgmental manner & respect their decision
- consider cultural influences on infant feeding
- provide affirming & respectful care to individuals who are part of sexual and/or gender minority populations
describe the presence of fluids in breast milk
- breastmilk = 87% water
describe supplementation of water for the infant
- never give baby plain water within 1st 6 months of life
- no supplementation w water is recommended
= breastmilk or formula only
what should be monitored closely in the early PP time? how can this be done?
- fluid intake & weight loss shoudl be monitored closely
- document voids, stools, daily weights, feeding times/amts
breastmilk provides the calories, nutrients, vitamins, and minerals required for infants with the exception of:
- vitamin D
due to the lack of vitamin D in breast milk, what is done
- vitamin D supp, 400 IU daily
describe vitamin K after birth
- we provide vitamin K injection after birth, then the infant will start making their own
B12 sufficiency with breast feeding depends on?
- depends on diet of individual feeding the infant
those with what type of diet need to supplement vitamin B12? why is this important?
- vegan diet –> should take supplements or it will be low in breast milk
describe iron in breastmilk
- iron is not high in any milk, but iron in human milk is well absorbed by infants –> no need to provide sources until 6 months of age
how many stages of lactogenesis are there?
- 3 stages
describe stage 1 of lactogenesis: when does it begin? end?
- begins in pregnancy
- ends with the beginning of increased milk production after delivery (start of stage II)
describe stage 2 of lactogenesis: when does it start?
- starts w the increase in milk production
describe stage 3 of lactogenesis: what happens and when?
- when mature milk is produced
- usually around day 10-14 after birth
the female breast is composed of?
- composed of 15-20 segments (lobes) embedded in fat & connective tissues
the female breast is well supplied with.. (3)
- blood vessels
- lymphatic vessels
- nerves
within each lobe of the female breast, what is present? what are these?
- alveoli = the milk-producing cells
what are the alveoli of the female breast surrounded by? what do these do?
- surrounded by myoepithelial cells that contract to send milk forward into the ductules
what occurs after the milk is sent forward into the ductules during lactogenesis?
- ductules enlarge into lactiferous ducts & sinuses, where milk collects behind the nippled
each nipple has? what function do these have?
- each nipple has pores through which milk is transferred to the ducking infant
after birth, the drop in estrogen & progesterone levels triggers?
- release of prolactin from the anterior pituiatry gland
what is the function of prolactin
= milk production
when are prolactin lvls highest
- during first 10 days after birth
describe the declination of prolactin
- gradually decline but remain above baseline lvls for the duration of lactation
prolactin is produced in response to.. (2)
- infant suckling
- “emptying” of breasts”
describe the “emptying” of breasts
- lactating breasts never completely empty
- suckling triggers positive feedback loop tp produce milk = milk is constantly produced as the infant feeds
what function does oxytocin have in lactogenesis
- stimulates milk-ejection reflex or let-down reflex
describe the production of oxytocing for lactogenesis
- as the nipple is stimulated by suckling infant, posterior pituitary prompted by hypothalamus produced oxytocing
describe the production of oxytocing for lactogenesis
- as the nipple is stimulated by suckling infant, posterior pituitary prompted by hypothalamus produced oxytocin
what is integral to lactation
- the nipple-erection reflex
what role does human milk play in the immune system?
- contains immunologically active components
= provides some protection against broad spectrum bacterial, viral, and protozoal infections
what is the major immune globulin in huamn milk
- secretory immunoglobulin A
what is a colostrum?
- first form of breastmilk that is released by the mammary glands
what does colostrum look like?
- clear, yellowish fluid
when is colostrum present?
- at birth
describe the concentration of colostrum (3)
- more concentrated than mature milk
- high conc of protein, fat soluble vitamins, and minerals
- extremely rich in immune globulins
describe the fat concentration of colostrum
- less fat than transitional or mature milk
what is transitional milk
- increase in amt of milk compared with 1st few days
what composition changes occur w transitional milk (5)
- immunoglobulins decrease
- proteins decrease
- lactose increases
- fat increases
- total calories increase
describe the composition of mature milk (3)
- fat content increases
- lactose increases
- protein decreases
compared w colostrum & transitional milk
