I'm usually a size 10. I put on 10kg's in the first tri with all 3 pregs. I put in 30kg all up for the first two babies and am on track for that again. I am usually really active but get pretty sick when preg and don't do much in the first tri. But each time I have lost it with minimal issues. It did take longer the second time, but if you are committed and work out, watch what you eat it will come off again. Your body definitely changes, but its not all bad. I don't have massive stretch marks or saggy skin. My friend who is the same age but hasn't had kids has a body not much different to mine. I think age us the killer, not pregnancy. Although my boobs will never be the same! But women can still be hot post babies.
