As a parent of a newborn, I always wonder if my baby ate enough or how often should a baby eat? I don't remember taking a class on how to raise another human while I was in school. All I know is that I have wants for my baby.

I want our baby to have enough nutrients and grow as they should.

I want our baby to be happy.  

I want our baby to eat and be the BEST version of themselves.

Always discuss these topics with your pediatrician but sources are cited below so you can learn for your baby!

 

Breastfeeding vs. Formula feeding

 

  • Infants should be exclusively breast-fed until at least the age of 6 mos (American Academy of Pediatrics recommendation)
  • Infants can be given commercially available low-protein infant formula IF no longer breastfed or no longer exclusively breastfed
  • Breastfeeding saves lives!
  • Breast is Best!

 

What are some advantages of Breastfeeding?

  • Baby immunoprotection- secretory IgA (sIgA), the dominant antibody in breast milk, stops pathogens from sticking or penetrating the gastrointestinal tract
  • Favorable gut microbiome- associated with reduced asthma and obesity rates
  • Lactoferrin- helps to absorb iron and promotes epithelial growth
  • Milk fat Globules- has antimicrobial properties and serves as vehicles for sIgA
  • Less Childhood obesity
    • Leptin- suppresses appetite and prevents overeating
    • Ghrelin- stimulates appetite and promotes self regulation in breastfed infants
  • Less respiratory and ear infections
  • Reduction in SIDS (Sudden Infant Death Syndrome)- 45% reduction in SIDS risk for newborns to 2 mos, those breastfed ≥2 months had a 62% reduction, and those exclusively breastfed for any duration had a 73% reduction
  • Less pediatric cancers- infants breastfed >6 months had a 24% reduction in risk of acute lymphoblastic leukemia compared to those not breastfed, while those breastfed ≤ 6 mo had a 12% reduction
  • Less risk of Type 2 Diabetes- nearly 40% compared to formula-feeding

 

What are advantages of breastfeeding for the Mother?

  • Postpartum weight loss
  • Less chance of reproductive cancers- 28% lower risk of developing ovarian cancer among women who breastfed for at least 12 months compared to women who never breastfed 
  • Reduced maternal bleeding after delivery
  • Suppressed ovulation- type of birth control
  • Bonding with baby
  • Free! Saves money

How many calories are in an ounce of breast milk?

  • Babies 12–23 months of age need an extra 550 kcal per day.
  • Note that more complementary calories may be needed as less milk is consumed
