our dd is 2 1/2yrs and she still has a bottle in the morning when she gets up (my dh gives it to her lol he is a sucker, she asks - he gives) and she has one at nighttime before bed, she loves her bottie before bed, sometimes she has her milk in a cup before bed. she only ever has milk in the morning and at night and it is something she enjoys.

my ds is nearly 7 and he still has a drink of milk obviously in a cup lol, every night before bed - not warm just cold, i guess i still have a drink of milk before bed to lol.

personally if it is not bothering you or your dd by having a bottle, then why take it away - they are only little for such a short time. sorry that is just my personal opinion
