For the first 2 to 5 days after your baby is born, you will make a small amount of colostrum. This is the early, thick, rich milk that is high in nutrients. Colostrum is all a healthy, full-term baby needs in those first few days. Around 3 to 5 days after birth, your milk will come in. But some things may delay your milk from coming in. These include:
Cesarean section (surgical) delivery
Excessive bleeding after birth
Infection or illness with fever
Strict or prolonged bed rest during pregnancy
Milk supply depends on demand, or milk removal, from the breast. The best way to have a good supply is to feed frequently, when your baby shows hunger cues. You may have trouble with delayed or reduced milk production. If that is the case, first take a look at the number and length of your feedings. Make sure that your baby can put their mouth around your nipple and areola to nurse (latch on). Make sure that your baby can transfer milk from your breast. If you are unsure about this, get help from a lactation consultant (breastfeeding specialist).
If you have a delay in your milk coming in, don’t give up. Continue to express milk. That means removing milk from your breasts with a breast pump or by hand. Breastfeed often. Do this even if you are supplementing with formula for a few days. Babies who are premature or jaundiced may be more likely to need formula for a short time.
Sometimes a health condition may cause a problem with milk production. It may briefly delay the large increase in milk production that often occurs 3 to 5 days after birth. This may cause a delay in producing large amounts of milk until 7 to 14 days after giving birth. If this happens to you, don’t give up. Seek support and guidance from a lactation consultant.
Don’t wait to get help if milk supply is ever a concern. The sooner you get help, the better. Many communities have breastfeeding support groups that can be a good resource. Contact your healthcare provider if you are having problems breastfeeding.
