After BBL - can I sit on a kneeling chair and let my butt hang out then get up every couple minutes on my 3rd day?

Thank you for your question. Every surgeon has a different post op protocol. Generally speaking avoiding pressure is always recommended. There are different ways of sitting down that help avoid pressure on the butt. Sitting on the upper back part of your thighs is a good way of avoiding too much pressure on the grafted areas. Using a cushion or something like a "bootybudy" on the back part of your thighs while sitting, will keep the butt elevated and avoid most if not all of the pressure on your butt.

For other specific information it is best to contact your operating surgeon as he is the best person to advise on your post-op care.

Best of luck on your recovery and Happy Holidays 

In order to give your fat graft a chance to 'take' you really should not be putting any pressure directly on the area which received the fat transfer. We advise our BBL patients not to sit (or drive) for three weeks following surgery and to wear a compression garment for the first two weeks.
Following your plastic surgeon's post-operative instructions as closely as possible is crucial for ensuring fat cell survival following your Brazilian butt lift, so consult with your surgeon to discuss what your specific best options are.
Best wishes!

Each surgeon is different in how they want their patients to recover.  Best too review the specifics with your surgeon.  Good luck!
