Congratulations on your pregnancy and the fact that you had no complications. The procedure itself is easily tolerated, it is essentially a liposuction. There is very little pain associated with it and the body recovers quickly. However, the fat grafts injected to the buttocks pose a challenge in that to ensure graft survival, we recommend the patient not sit for 3 weeks. I think the main obstacle in your particular case is, who is going to take care of the baby while you are recuperating? While recovering you are not going to be able to enjoy the baby as fully as you could if you could devote your undivided attention to the baby. If it was my daughter, I would recommend waiting a few moths, at least until the baby can easily be taken care of by whoever is going to be helping you., because you are going to need help during the recovery period For more details on the procedure check the link below and watch the video.
