Dear Mom,
I gave my kids a bottle for as long as they asked for it, and their teeth are fine,
My boys eventually weened themselves off of it, by sleeping thru the night, and then last was the Before bed bottle,
My baby uses a pacifier and he is 2 I let him have it,
And during the day we use the silicone STRAW sippy cup that resembles a bottle.
from there we graduated to a regular silicone sippy cup,
and finally a regualar cup, which is where we are, NOW
Only thing is sippy cup gives them freedom to travel around
and cups are at the table only,
So i suggest you buy the silicone straw sippy cup, for the days, and a bottle still at bed time,
then after she has a few weeks with e sippy cup, you can hide the bottle and offer just the sippy straw bottle,
and then after a month or 2 when the sippy cup gets damamged or something, give her the regular silicone sippy cup during the day and the straw for bed
and then after a week or 2 just the sippy cup,
and after a month, a regular cup, and sit her up for a drink of water from the cup,
and eventually she won't need anything
but it takes time to transition her, unless you do it cold turkey, which is the cry it out method,
Good luck
M
