hi there, I think that if she doesnt walk around with the bottle sucking on it constantly, then thats all good, I was always told to aim for the bottle being away by max age 2, if she just drinks it quick then its fine, but you can always give her some in the cup and some in the bottle if you want to
and then gradually increase the amount in the cup until its all cup
As for it being warm, yes thats fine if she likes it that way
I went to cold milk just after a year as Abbi didnt mind, but if you dont mind warming and she doesnt then keep with warm
just means you have to do it
