I thought I was one of the lucky ones as I didn't put on too much weight while pregnant. Maybe 10kg but most of that was baby. I exercised throughout the pregnancy and didn't eat too much junk. After Lewis was born and I started breastfeeding (with great difficulty, but that's another story) the weight just dropped off me. I remember thinking "this is easy" and wondering why my Mum had so much trouble with her weight after having us.
