Weight loss help..

I have two little ones, both delivered by c section. The first I got my body back by barely eating, now I’m on meds that make me hungry all the time. This time around I have an ugly saggy belly covered in stretch marks & I just feel disgusting. I drink only one or two cans of pop a week, I also eat pretty healthy. But I have no time to hit the gym. So my question is does anyone have any tips on food choices, working out at home, etc anything that will help me get back into shape..
