After a mommy makeover when you can sleep on your back?

Sleeping on your back is the best position possible for healing and for most people most of the time.  It is anatomically correct, doesn't contort your spine like belly and side sleeping and wont misshape your breasts or face.  You are smart if you choose to sleep this way and make it even more comfortable by placing a few pillows under your knees to put you in the chaise lounge position that even our astronauts go to space in.

In my practice, immediately. Now.....most people will be more comfortable with their back elevated for a number of days, but I let them choose whatever is least uncomfortable for them. You should ask your surgeon as only she/he knows your specific case.

This question is best answered by your surgeon since there are different types of tummy tucks. In general, once you are standing up straight comfortably, it should be safe to sleep on your back. That is usually between one and two weeks post-op. Good luck!
