Dd3 is 4 months and I'm trying to get her to drink from the bottle, problem is she is being extremely stubborn!! I've tried expressed milk and formula, even a mix of them at the same time.. I'm now using a nipple shield to get her use to the rubber but she hates it and its so hard to get her to feed but once she's on she's ok until she slips off!! So how long did it take to ge your stubborn bub to take a bottle? I have until the 19th feb to get her to as I have a 4 day workshop at my uni..
