Harjacmum - I am also a bigger girl, and have been very stressed in my previous pregnancies about putting weight on. Well I got through both pregancies without putting more than 1 kilo on either time, and all I did was make sure I ate healthy (which I actually do already) and kept active with walking etc. The bonus is pretty much as soon as you give birth you lose 10 to 15 kilos!

My Obs has always been great and never referred to my weeight, other than when I brough it up, and even then he just said that the less I gained while pregnant the better, and that bubs will always take what it needs first!
