Typically, a mommy makeover includes a tummy tuck and most patients feel comfortable when sleeping in a slightly flexed, or bent position, while on their back. This can be done by placing pillows under your back and your knees. I advise my patients to do this for the first couple of days but gradually they will feel less tight and they are able to sleep flat on their back. Good luck!
The key element to a Mommy Makeover is the tummy tuck. A well done tummy tuck requires significant tightening of the abdominal skin, and therefore for the first 3 days after a tummy tuck, if you were my patient I would recommend sleeping with between 35-45 degrees of flexion at the waist. In bed, this is accomplished usually with pillows behind the back and pillows under the knees.A second choice which many of my patients have recommended is the use of a recliner chair which gives the flexion required as a integral part of the settings of the chair. In my office, we refer to this flexion as the lawn chair position. We have patients remain in the lawn chair position for 72 hours, and then after that, they can either lie flat on their backs or in some degree of fetal position on their sides until they feel comfortable lying flat.
