we waited until DD was 3 1/2. She did it very easily at that age. (she was similiar to your DD and had it at home but not daycare). We talked about giving it up for a few weeks and then promised her a toy if she gave it up - she wanted a bike horn (honker). Anyway, she said she was ready to give it up and threw it away but about an hour later wanted it back. We gave it back and told her it was ok, we would try again the next night. The next night she threw it away and never looked back. After a day she got her honker and played w/ it for a few days and then moved on to something else.
