Colostrum is an "early" milk that your breasts begin to produce during the last few months of pregnancy.
It's denser and lower in volume than regular breast milk but loaded with protein and antibodies.
Some women aren't aware of a change in size, while others can go up several few cup sizes; each experience is unique.
Veining in the breast, bigger nipples, sensitive nipples All of these changes are in preparation for nursing your baby.Colostrum During your last trimester, your breasts might begin to leak a small amount of colostrum, which is a thick, yellow substance.That's why a good, deep latch is essential for your baby to access as much milk as possible.Engorgement Your sore, swollen breasts have come back, but take heart—this phase only lasts for a few days.This process is called "let down." Let-down Breasts have the ability to help feed your baby so she doesn't have to work so hard throughout the whole feeding to get the milk from your breast.
When you're having a let-down, the milk is being squeezed into the ducts by contracting muscles and results in an increased flow of milk, making it easier for your baby to access it.Oxytocin This hormone is the workhorse and has a starring role in both the birth process and breastfeeding.It makes muscles contract and is responsible for creating contractions during labour. Nipple stimulation (such as your baby latching on) creates an oxytocin rush as well, which not only causes continued uterine contractions for a few days after birth (that's a good thing because it helps shrink your uterus back to size) but also causes the muscles surrounding the milk-producing cells in the breast to contract, squeezing milk into the ducts.About 2 or 3 days after you give birth, your mature milk comes in.This process increases the blood flow to your breasts, and the surrounding tissue starts to swell. Your breasts will soon adapt to your baby's needs and produce the right amount of milk, plus they'll become softer and less painful.If you ever have any concerns about the changes you're experiencing, talk to your health care professional.
