my 4 month old DD was having really frequent night wakings, i put it down to the dummy, but who knows... i have started co sleeping, and it has taken quite a few weeks for it to work for both of us, but i am so much more relaxed now as i know if she wakes it is easy to cuddle her and she goes back to sleep, i dont even have to get out of bed. last night i tried sleeping without her (as she was asleep in her cot) but found i couldn't sleep! never thought that would happen, as to begin with, it was difficult to sleep with her. good luck whatever you decide to do. sometimes u just have to do what works 'right now' and not worry about tomorrow.... for me that was taking her into my bed.
