Do breasts shrink after weaning?

My breasts are much smaller after 10 months of breastfeeding. Why did this happen? Did breastfeeding cause me to lose two cup sizes?

Breasts do not shrink after extended breastfeeding. Immediately after weaning your little one from your breast, you may find that they appear "deflated". Your breasts will become fuller, and closer to the way they were before, as fat is again deposited.

Breastfeeding often is blamed for changes in the appearance of the breasts. Actually your genetic predisposition, skin elasticity, amount of weight gain, and pregnancy history have more impact.

You will probably find that about six months or so after weaning, your breasts will become fuller. Of course you know that you are not responsible for any decrease (or increase) in breast size. This very likely has been genetically determined. (You might want to ask your mother or sisters if they had this same experience. Other than checking with close family members to find out if this tendency exists, I know of no other way to predict these breast changes ahead of time.)
