I didn't put on much with either of my girls - 5.5kgs with DD1 and only 2kgs with DD2. I was overweight to start with, so that certainly played a part in it, but mostly its that I just don't "do" pregnancy well. I'm sick for 9 months and my body apparently does a terrible job of leaving anything at all for me after feeding baby. My girls were born average - 3.5kgs and 3.6kgs - and I walked out of hospital considerably lighter than pre-pregnancy.

I've joked that pregnancy is the best diet I can ever go on, but in truth its a pretty high price to pay.

I think so long as you are eating healthily, getting exercise if health allows it, then you really shouldn't stress. What's important is that you look after yourself and your growing baby. Don't forget that once bubs is born you're going to be running around like a crazy person looking after a newborn and 3 boys!
