This might be a stupid question, but here goes. My bf-ed ds (3.5 months) is not great with a bottle (fusses, takes in air, gets wind, cries, refuses bottle). A few times I've taken the teat bit off and given him the milk from the open top of the bottle, which he seems fine with. I've also tried one of those first stage Tommee Tippee ohes which has been more successful than a bottle. Is this okay?
Yes, it's fine The only problem being it won't fit in all sterilisers - but then some people say you don't need to sterilise at all if you wash things properly. I haven't bothered sterilising when I have given expressed milk because I just put it into the bottle immediately before feeding it.
