My 23 month old is currently having 2 bottles of milk a day - Before her afternoon nap and when she goes to bed at night.
I generally give her the bottles and leave her to drink them and fall asleep by herself.
I know it will probably be easy for me to give her milk in a cup instead of a bottle and get rid of the bottles altogether, but what happens if she wont go to sleep without a bottle? How can I teach her to drink her milk before she goes to bed and then just go to bed? Or, should I try in preparation for TT to not give her any milk right before bed?

How did you wean your toddler off the bottle? How old were they? How long did it take?
