Hey Mrs CC I remember you from cc section. Wow can't believe your about to meet your baby! I cc on and off during pg ate about the same as you couldn't stick with sw its too hard and I felt more restricted on it.
If you have a natural birth no complications etc, once you feel well enough you could start going out for walks with baby in the pram, don't do anything to soon, I waited till 5-6 weeks before rushing back into dieting, but I was recovering from section after 2 weeks I started going out for short walks etc. They do say you should wait till after your 6 week check before starting proper exercise.
After my second baby who is now just turn 3 I gained 3 st but most of weight did come off after birth sometimes you gain the weight that you need, my weight gain was in between pregnancies really I gained 4 st in a year almost 5 yrs ago and never could shift it until now, I would say try not to worry about your weight at the moment concentration on meeting your new baby cos it really is amazing.
I'll look out for announcement, good luck for the birth hope it all goes well xx
