ive never counted calories or anything like that...i know they say the whole 'eating for two' thing is a bit of a myth, but obviously you will eat a bit more than you normally would. i think the main thing is the quantity of what you're eating. if you're eating a lot of healthy things like fresh fruit and vegies, and healthy snacks, then go for it. but at the end of the day its about what you think you can stomach and what you're able to eat. i have eaten a fair bit of junk with this baby lots of chocolate and chips and stuff.....but i feel fine so what the hey?
