How Do You Sleep After a Tummy Tuck and Fat Transfer to the Butt?

Thank you for your question. After a tummy tuck I would recommend you to sleep flexing the knees to avoid tension. I also recommend you to follow your  PS post op advises.Respectfully,Dr. Emmanuel Mallol Cotes.-

You don't want to sleep on your back. Try sleeping on your side with something to prop up your back. Keep flexed as well for your TT.

By laying on your side and transferring on all fours, it should be possible to remain flexed at the waist while avoiding pressure on the incisions and buttocks. You will find that you may have to switch every hour or so. You should discuss this with your surgeon.

Hello dear!!
Thanks for the question and provided information as well. 
You can adopt the position that best suits you and in which you feel most comfortable, preferable on the sides. It helps to use several pillows to accommodate yourself 
If you have any concerns, please follow up close with your plastic surgeon.
Good luck :)

Talk with your surgeon but it may be best to sleep on your side, turning every hour or so for comfort.

Patients may sleep in any position after Brazilian Butt Lift. However, when combined with a tummy tuck it is best to keep the pelvis slightly flexed and to place a pillow beneath the knees.
