Bye Bye baby flab and tummy. Want to join me as a friend?

I look 4 months pregnant after having my last child. Someone asked me if I was pregnant over Christmas. I was upset. Time to lose fat and tone up my tummy and hips. I don't want to be like this forever. Anyone with post baby tummy want to join me? If anyone has beaten the post baby tummy please support me as I'd love some advise and encouragement. Thank you.
