How long do I have to wait before getting liposuction after having a baby?

I recommend waiting approximately 6 months to allow your skin and weight to stabilize.  Liposuction is a great option to remove unwanted areas of fat.  If you have loose skin, a skin tightening procedure may be needed.   

Pregnancy and delivery take a toll on your body. Please allow yourself to heal at least 3 months before considering a body-contouring technique such as liposuction. You may not like your body shape directly after delivering a baby, but could find that you go back to your pre-baby shape on your own after a few months. Breast feeding and exercise should help you regain your shape. If you are still unhappy with your shape and would like to permanently re-contour your body, you may also want to consider noninvasive fat-elimination techniques, such as Vanquish, CoolSculpting and ThermiTight. Please consult a board-certified dermatologist who can help you find the perfect fat-elimination technique to help you get back into shape once you're ready to do so.

Thank you for your question. After giving birth you'll need 6-9 months to have surgery and you should be no longer breastfeeding.
