Swollen Breasts 3 week old

Hi Doc,

My baby girl is three weeks old and I've noticed that she has quite swollen breasts, is this normal or should I have it checked out?

This is normal and will disappear by itself. It is an hormonal effect carried over from the pregnancy.

Swollen breasts are present during the first week of life in many female and male babies. They are caused by the passage of female hormones across the mother's placenta. Sometimes the breast will leak a few drops of milk, and this is normal. Breasts are generally swollen for 2 to 4 weeks, but they may stay swollen longer in breast-fed and female babies. One breast may lose its swelling before the other one by a month or more. Never squeeze the breast because this can cause infection. Be sure to call your health care provider if a swollen breast develops any redness, streaking, or tenderness.
