Honestly, I don't personally think it makes a huge difference. I always thought you're more likely put the weight on, than passing it on to your baby (if that makes sense?). That your body 'distributes' the energy, and any 'excess' goes to you? (Obviously its probably more technically stuff to it than that, but thats basically what I always thought).

Of course, its best to have a good diet, but thats for the nutrient value more than the avoiding 'bad' foods thing... I doubt a balanced diet with the odd piece of chocolate or cake is going to make a 10lb baby!

Unimum, fro mmemory that mum had gestational diabetes, which increases the risk of larger babies, but doesn't have much to do with what she ate, more to do with how her body dealt with what she ate KWIM?
