Colostrum is high in protein and immune-modulating nutrients. Many people think it’s higher in fat, but it’s actually higher in protein. Colostrum is the first milk produced; most people call it liquid gold. It’s easily digestible and helps baby release the first meconium.

Breast milk is made from blood. This is why things that mom eats affect baby. So, if mom’s gut is damaged, bigger particles will pass into her blood and then on to baby, making it harder for baby. Leaky gut in mom affects baby.

Milk production is initially driven by expulsion of the placenta, either vaginally or via C-section. Progesterone is up during pregnancy; when the placenta comes out, progesterone drops and prolactin increases, and that is what makes our milk flow. Oxytocin is what helps our body let down milk.

  • Oxytocin is triggered by smelling baby’s head; it informs your brain and body what nutrients baby needs.
  • Baby-wearing and bed-sharing help bond with baby and support milk production.
  • When baby is born, they can see 8–12 inches—the same distance between the breast and mom’s face.
  • Milk is a living fluid. Nutrients, vitamins, minerals, and growth factors all change minute to minute based on baby’s needs in the moment.
  • Immunoglobulins are passed through breast milk, helping protect babies against diseases.
  • The nipple is a two-way valve. The nipple will pick up information in baby’s saliva and produce milk based on baby’s needs.

Milk production is triggered by emptying of the breast. The longer you let milk sit in the breast, the less milk production you will have!

Prolactin and testosterone work in opposition. This means if you are going to do HIIT workouts and CrossFit, you need to balance it with yoga, baths, and relaxation. When testosterone goes up, prolactin goes down.

Chiropractic adjustments help stimulate the parasympathetic nervous system. This helps calm momma and decreases her cortisol, making breastfeeding more enjoyable.
