Admittedly my initial suggestion would be to not worry one iota about losing weight for a few weeks after you have bub. You've got enough to worry about .

I waited until my DS2 was 9 months and started weight watchers. I lost 10kg, but put 1.5kg back over a two-month period (Dec-Jan). My goal was around 10-12kg, which puts me back at pre-baby weight and within a healthy BMI range. I'm now working on the last 4 kilos, which would see me shed the 12kg I wanted to.

Exercise was/is the key for me - either throwing the kids in the double pram and hitting the footpath, or getting on the treadmill. I also find it I pay close attention to my portion sizes that helps me lose weight. I can be pretty nifty at throwing heaps of food on a plate!

Good luck with bub's arrival and losing your weight. It's not much fun feeling overweight after a bub, but don't go toooooo hard on yourself first up

PS: March 16 is a great date for a bub ... my DS1's b'day!
