Well Lily has been waking once in the night, anywhere from 2-3am for that feed. But she is also cutting her 3rd bottom teeth AND it has been quite cold, so I don't know if she is waking for the feed or other reasons. I will keep skipping her 8.30pm DF and just see how we go over the next week or so. If she's still waking, I'll go back to giving her the DF and see if she goes back to sleeping through, then I will know for sure.

Thanks for everyones input
