We had a similar problem, but she was waking every2-3 hours and at around 8mths I decided that I would not feed at all over night anymore between 7 and 5. So we went in and cuddled, patted, rocked etc... and yep she did cry once she realised there was no booby coming but we still comforted her during this, and it only took a few nights for her to realise and to start sleeping better. It is really tough though and you need to be prepared for some pretty yucky nights, even with the cuddles and pats etc...

It is up to you hun, but I guess the key is to be consistent, once we decided there were no more feeds, that was it, I didn't want to confuse her by feeding her some nights and not others.
Good luck with it all hun!
