I put on 25+ kilos with DS and was back to normal by the time he was 9 months old - that is WITHOUT any exercise or special diet. I was breastfeeding fulltime though. With DD i put on 15 kilos and i'm back to normal with no exercise or diet and she is 15 weeks old, again, i am breastfeeding full time. I will add that this time around, even though the scales say the same amount i'm definately a bit "looser" around the middle. If i can find some pics i'll come back and post them for you. xx
