Newborn Nutrition & Feeding Ch 27 Flashcards
Other than establishing a basis for healthy eating habits, what is newborn feeding good for?
Provides an opportunity for social and psychological interaction between parent and infant
What are the recommendations for infant nutrition?
Breastfeed exclusively for first 6 months
Can start incorporating foods after 6 months in addition to BF (BF max of 2 years)
Supplement with vit D until 1 y/o
Infant formula should be iron-fortified
BF should be on-demand and baby-led
T or F: Human milk is nutritionally superior to alternative food sources for infants
True because nutrients in breast milk are more easily absorbed than in formula
What are the benefits of BF to Infants
- Enhances maturation of GI tract & contains immune factors that contribute to lower risk of disease and obesity
- Lowers risk of certain allergies
- Lower risk of sudden infant death syndrome (SIDS)
• Easily digested and absorbed
• Laxative effect
• Neurodevelopmental advantage
• Analgesic effect
• Better facial, oral and speech development
What are the benefits of BF to mothers
- Decreased risk of some chronic diseases (certain cancers, r.arthritis, T2 diab, CVD, hypertension)
- BF promotes involution and is associated with a decreased risk of PPH
- Tend to return to their pre-pregnancy weight faster
- May protect against osteoporosis and hip fractures
- Provides unique bonding experience, enhances maternal role development, may provide protection against PPD
What are the general benefits of BF to the family
- Convenience: no need for other equipment
- Portable: no supplies needed to be carried
- Saves money: no need for other purchases
- Parental absenteeism from work is decreased
What are some contraindications to breastfeeding
- Chemotherapy or radioactive isotopes
- Active TB or Varicella
- HIV
- Substance abuse (e.g., cocaine, marijuana, etc.)
- Herpes lesion on a breast
- Human T Lymphotropic Virus
- Certain medications
- Chaga’s disease
- Hep A, B, C
- CMV +
- Infant galactosemia
- Infant metabolic disorders
What is breastmilk composed of?
87%: water 13%: • Immune factors • Growth factors • Proteins (approximately 70% whey and 30% casein) • Digestive enzymes • Fats (variable) • Carbohydrates (predominantly lactose) • Vitamins (A, B complex, C, D, E, K) • Minerals
What are some risks of not breastfeeding for the infant?
GI infections Otitis media Atopic dermatitis Respiratory track infections Asthma (no family history) Childhood leukemia Celiac Disease Ulcerative Colitis Crohn’s Disease Atherosclerosis Hypertension High cholesterol Reduced immune protection Obesity Lower cognitive function Type 1 and 2 diabetes SIDS
What are some risks of not breastfeeding for the mother?
decr oxytocin = decr involutoin = incr risk of PPH
increased risk of ovarian, uterine, breast cancers
increased risk of developing T2 diabetes
increased chance of developing chronic conditions
Why was the Baby Friendly Health Initiative (BFHI) created?
“Protect, promote and support bf
Remove hospital barriers to breastfeeding
Provide evidence based training of health care workers
Promote an international standard
Baby friendly designation is achieved when:
Free or low cost substitutes are not accepted
Feeding bottles and teats are not accepted
Successful implementation of the 10 steps
What are the 10 Steps to Successful BF?
- Have a written breastfeeding policy that is
communicated to health care staff. - Train all health care staff in skills necessary to implement this policy.
- Inform all pregnant women about the benefits and
management of breastfeeding. - Help mothers initiate breastfeeding within half an hour of birth.
- Show mothers how to breastfeed and how to
maintain lactation, even if they are separated from their infants. - Give newborn infants no food or drink other than breast milk, unless medically indicated.
- Practice “rooming in” allow mothers and infants to remain together 24 hours a day.
- Encourage breastfeeding on demand.
- Give no pacifiers or artificial nipples to breastfeeding
infants. - Foster the establishment of breastfeeding support groups and refer mothers to them on discharge from the hospital or clinic.
What is Lactogenesis and what are the 3 stages
The synthesis of breast milk
I - differentiation
II - activation
III - maintanence
When does the first phase of lactogenesis begin and what occurs during that period
Differentiation occurs mid-pregnancy
Prolactin (pregnancy hormone) stimulates cell differentiation so that the breast will be able to produce milk.
Progesterone inhibits the onset of copious milk secretion
When does the second phase of lactogenesis begin and what occurs during that period
•“Milk coming in” aka transitional milk
• Changes in hormones after birth of the placenta (30 40
hours after birth) cause this
- Decrease in : progesterone, estrogen, placental
lactogen
- Increase in : oxytocin and prolactin
• Feedback inhibitor of lactation (FIL)
- Small whey protein that acts as local negative
feedback mechanism
When does the third phase of lactogenesis begin and what occurs during that period
- Establishment of mature milk
- Dependent on effective removal of milk from breast supply and demand
- Whiter, thinner than transitional milk
- Mature milk = fore milk + hind milk gradient
Colostrum
Thick, clear to yellowish in appearance
Available at birth up to 2-3 days postpartum
2 - 20 mls /feed
Low in fat and sugar, high in protein and minerals
Contains IgA
Easily digested, laxative effect
Transitional Milk
Present 2-5 days to 2 weeks postpartum Less yellow in appearance than colostrum Dramatic increase in volume Higher fat, lactose and calories than colostrum Less protein than colostrum
Compare Fore Milk vs. Hind Milk
Fore Milk:
- Bluish white in appearance
- Low fat; high water content milk that comes at start of feed
Hind Milk:
- creamy in appearance
- High fat and calories; released well into feed
- Satisfies hunger, promotes weight gain, content between feeds
- Stools have seedy appearance
What causes milk production hormones to be released
Suckling on the breast (stimulating the nipple, areola and grasping at the breast) causes milk production stimulating hormones to be released from the brain
What are the two hormones related to the stimulation of milk production
Prolactin - causes alveoli in breasts to begin milk production
Oxytocin - contracts the muscle cells around the alveoli and causes ‘let down’ which sends the milk down the ducts to be available to the infant.
What are some stimulating and inhibiting factors for the Milk Ejection Reflex (MER)
Stim: Hearing a baby cry Thinking about the baby Preparing to breastfeed Being the usual time the baby feeds
Inhibit: Fear Pain Embarrassment Anxiety Breast surgery
