“I was wondering when my milk will come in? I had my little girl on Tuesday and still no milk. I’ve had to supplement with formula now because she isn’t getting enough.”

Two things here.

First we need to establish whether the baby actually isn’t getting enough.

Sometimes mothers assume they don’t have milk, or don’t have enough milk, when the truth is their milk supply is just fine.

Second, we need to talk about what it means for the milk to “come in”.

My first question is, how do you know your milk hasn’t  “come in” and that your baby isn’t getting enough?

How old is she and is she producing wet and dirty diapers? What comes out must have gone in.

While we often use the phrase “come in” when we’re talking about a postpartum mother’s milk supply, that term is somewhat misleading and inaccurate.

Your breasts have milk even before you give birth.

Typically, sometime in the last trimester your breasts start producing colostrum (the early milk that is rich in immune factors), so the term “come in” really isn’t accurate.

What happens when someone refers to a mothers milk “coming in” is when the milk turns from colostrum to mature milk and changes in volume (it dramatically increases) and in color.  Colostrum is a clear to yellowish color and then turns to mature milk which is a milky white – typically around 3-8 days postpartum. It’s at this time that some mothers experience engorgement.

It’s very important to not limit a newborn infant’s time at the breast. The more time the baby the baby spends nursing, the more quickly the colostrum is removed and typically the faster the mature milk comes in.

The second issue is figuring out whether the baby is getting enough milk.

If your baby is producing enough wet and dirty diapers then you don’t need to supplement. Supplementing with formula may not be necessary, and can actually decrease your existing milk supply.

My advice to this mom is to speak with a lactation consultant or a La Leche League leader who can observe her baby nursing to see if there are any obvious problems with positioning or latch. A baby who is not latched on well may not get enough milk at a feeding and also won’t sufficiently stimulate the mother’s milk supply.

I also suggested that she allow plenty of time for her baby to get her tummy filled. Some babies are quick eaters and some aren’t. Especially during the early weeks, it may take 20 minutes or longer for baby to get enough.

Make sure she isn’t sleeping at the breast and is actively nursing (sucking and swallowing) for the entire feeding before allowing her to nap. And don’t attempt to schedule a breastfeeding baby, especially while she is still learning how to feed.
