Baby will only take bottle from me!

[sophielouise]

I've persevered with DD2 since she was born and given her one bottle of formula a day when BF the rest of the time. She is finally drinking a decent amount and takes it at bedtime now with no BF. (This was done due to the experience of DD1 being a bottle refuser and as a result I could never go out at bed time for about a year.) Anyway, annoyingly she is now refusing said bottle from anyone else except me! Rather annoying! She is 6 months old, and on 3 meals a day. She won't take it at nursery (I'm doing my KIT days once a week at the moment), nor from her Daddy. Any tips please? Does it matter?
