Mommy Makeover Surgery after 4 kids

My fourth is due Sept. 18 ‘18. I can lose some weight (after pregnancies) with exercise and eating healthy, but I have difficult time losing it. I know it doesn’t solve major weight loss. But after losing some I have lots of loose skin and saggy boobs. I also have a scarred over abdominal wall separation and it still pushes out when not pregnant. I’ve been thinking about this surgery for 5/6 years and have done a lot of research. I’m 28. Almost 5’. Also, I do know it’s personal preference. Lol I don’t think I’m ugly. I just don’t feel physically put together.
