I agree with PZ. It is important to be there for your baby. But, if you can, give her a chance to settle herself before helping her, at least on some sleeps. I made this mistake with my DS. I found I had to rock him to sleep every sleep until he was over 12 months. I believe this is because we never gave him a chance from an early age to learn that he could do it himself. My DD's 8mths now & she occasionally settles herself. Most times she needs a bit of help from us though, a feed, a cuddle, bum patting, whatever works.
