Pretty much what everyone else said! I am 5'1 so a bit shorter and post DS was 70kgs which was the biggest I had been (I hit 80kgs in pregnancy and that was a 20kg weight gain for me) and I felt too big for ME. I would have wanted to lose weight if we had contemplated having a 3rd but again it depends how you feel and if you feel fit and healthy. My healthy weight for me at this height is nearer to 60kgs which I am now, although I haven't been exercising so I don't feel fit and healthy ITMS even though I am around 63 kgs. Good luck with it and as others said it is only you who can decide but being fitter and healthier - without a focus on weight can only be a good thing (not saying you aren't!)
