How long should you have to wait until you can get breast implants, after having a baby?

Till done nursing...: And until breast size has stabilized, as breasts often "deflate" after pregnancy and nursing.

>4mos after nursing: I usually advise my patients to wait approximately 4 months after completing nursing before considering breast augmentation. Even then implants may trigger a brief bout of galactorrhea (milk production).

Typically 3 months: We normally say to wait 3 months after having a baby before having any cosmetic surgery procedure. The body needs time to heal and recover from giving birth.

4-6 months: I would recommend you wait 4-6 months after you stop breast feeding. That way the shape/size of the breasts have stabilized. It makes the results of the surgery much more predictable and enables the surgeon to more closely reach your expectations.
