My DD is 4 months old next week and is BF. From 6 weeks DH and I have been doing 1 expressed feed a day, normally the dream feed, so that I could go to bed early or very occasionally go out. This has never been a problem but for the last two or 3 weeks DD has been rejecting the bottle, it started as just playing around, pushing the teat around her mouth instead of sucking but now she does that and cries and cries until i eventually have to feed her. She rejects every bottle we try now. We want to continue mixing BF with EBF bottles and eventually start introducing formula from 5 months to give me a bit more freedom and also its nice for DH to be able to feed DD. I am also worried as from 6m i need to put her in nursery. I am trying out different bottles / teats (we were using Avent and are currently trying Tommee Tippee closer to nature) but its not working yet. Any advice please?
