Recommended Waiting Time Between Breast Implants and Brazilian Butt Lift?

Ive scheduled my breast augmentation on May 19th with a local surgeon that's really good. I contacted the surgeon that I'm going to use for lipo and fg to set up date for June 16th. I let him know that I was having my breast done a month before. I was told that I needed to wait 6-8 mos between surgery because if possible risks due to anesthesia. I really wanted to get all of this out of the way before summer ends. He suggested giving me a package to do the implants at te same thing, but I'm sticking with my initial surgeon. I don't know what to do now. I was trying to set up the lipo for 4-6 weeks after my BA. I brought this concern up with the surgeon doing my BA, and he said I shouldn't have an issue doing it the way that I'm planning. He said that I'm healthy, and it's enough time between surgery. What do you think? Is it enough time? Is it better doing the breast augment before the lipo/fat graft? Would it be okay to sleep on my chest 4-6 weeks following my implants?
