Feeling confident after baby.

How do you ladies build your confidence after baby?

My stomach took the brunt of the warping (obviously) during pregnancy, my son made my belly button go completely inside out, and I got a lot of stretch marks around it.

I’ve been really struggling with the way my stomach looks now. I am down to my pre-pregnancy weight (121) which wasn’t a weight I was previously happy with either. But I was wondering what kind of diets/exercises could help my tummy/love handle area the quickest?

I am going to Florida in September/October and I just want to feel comfortable showing my stomach. Thanks.
