Should I have to do anything to make it move? It seems like the only time the baby moves is when I drink a cold drink or eat something really sweet.

I've just had a drink of Coke, and baby moved, which is good, but should I have to do that, or should baby move by him/herself??

Thanks for that too Nellie- makes sense to me about the lack of room, but I'm a paranoid first time mum!
