Has anyone had a BBL WITHOUT a tummy tuck?

Hi ladies!! I am going to see Dr. Tania Medina in the DR. However, I have not decided on a tummy tuck or a only Lipo. I really really do not want Lipo and I plan to have more children.What I really want to know how much loose skin are we talking here!!??My stomach doesn't hang over and I can feel the muscle underneath. So maybe the skin won't be so bad?? Help!!
