Just curious if anyone has had a similar experience.

I'm currently 3 weeks postpartum. I only gained 17 lbs during my pregnancy (not sure how I managed that!) and I'm already a little below my pre-pregnancy weight. The thing is, I have a bunch of loose skin around my tummy and I don't think I'll be able to fit into my pre-pregnancy clothes. I'm guessing this is just going to require some toning up.
