I let kids have the bottle until they are ready to give it up. My son had his till HE was ready to give it up. Bottles, especially if they are filled with milk, are a comfort for babies and toddlers. So I wasn't going to take a comfort from him. He took juice and water out of a sippy but wanted his milk in a bottle. He gave his bottle up in December; he was 2.5 years old exactly. His teeth are perfect too. I had my bottle till I was 4 and my teeth are fine. And the AAP even says...
"Many mothers are bottle-feeding their children beyond age 2, even though pediatricians often recommend the bottle be given up by 12 to 18 months, according to a California study of 191 healthy full-term infants.
Researchers found 42 percent of 2- to 3-year-olds were fed about three bottles a day, and 16 percent of 3- to 4-year-olds were given an average of 2.1 bottles a day."
