Today when I was giving my daughter a bath I noticed that she has a lump (about the size of a grape)in her left breast. I have never noticed it before. Is this normal? What is it? Has anyone else had this happen to their daughter?

Thanks so much.

What can I do next?

My daughter had the same thing, just before I started my period again. It went away within a couple of months. Our md said as long as it does not seem to bother her, is not red or hot, and she is not running a fever (unrelated to anything else) that we didn't need to worry about it. Some newborns have them when they are born. It is related to the mother's hormones.

Hi Jessica,

I can tell you that all babies appear to have a small breast bud after birth. Don't quote me on the cause (it's early and I haven't looked it up recently) but I believe it may be related to maternal hormones. I have read that some babies even leak milk from their breasts after birth. I'm not sure how long it takes to go away.. my 4 month old still has these little breast buds, but what would concern me is the size, and if it's not equal on the other side. I highly doubt it's something dangerous, but in any event I would put a call in to your pediatrician to see if they have any ideas.

Good luck!

Hi Jessica, I noticed the same thing in my daughters left breast when she was 5 months old. I called her ped. and she said as long as it's not hot/swollen/leaking or bothering her it could wait until her 6 mo. check-up. At her 6 mo. check up her ped. said it was caused by hormones - there's a name for it, but I can't recall what it is. My daughter is almost 8 months old now I noticed a few weeks ago that it's gone. I'd try not to worry about it and just keep a close eye on it. Good luck.
