Saggy belly

I just read a post that made me wonder about my PP body. Any women out there who are petite, (I am 5‘3“ 105lbs) who had a big pregnancy but were able to bounce back after? I just read a woman‘s post who was freaking out about her saggy belly and being the idiot that I am, I read the post all the way through and now I’m being irrational.

Anyone help calm me or give me tips to avoid a saggy belly?

And don’t tell me it’s inevitable or that I am being vain, thats not going to help me, it’ll only make me feel worse.
