Dd1 still has a bottle at three, she drinks juice and water from a cup now but likes her milk in the bottle like her sister, also before bed line you. It's no big deal to us really, her teeth are fine she will drop it when she is ready. I don't mention it to the mchn as they claim life will be easier if one child drops a bottle for a sippy cup, I don't see why when it's before bed and it still needs a wash anyway.
