Bella sleeps through mostly evey night but if she does wake up and is unsettled I take her out to the lounge and just sit on the couch and most times she goes back to sleep in my arms and then I put her back to bed - if not I will feed her but she generally only takes a few sips and then she is asleep.
When she was first teething she was having a feed over night for a bout a week and then when she has a growth spurt she has a feed but now she sleeps through from 6.30 - 7 evey night with out a feed. But bubs are all different and if they need a feed then so be it! If Bella desided that she wanted a feed over night I would not deny her that just to get her to sleep through.
