how old should a child be to stop drinking bottles to and after bed times, coz ma little sister was 1-2 years old when i stop her from using bottles during anytime of the day but a friend of mine who has a kids, her kids still use bottles during the day and they are around the age of 2-4.

hmm true, that's what i thought and i just see it as a sad thing that a child from the age of 2-10 still use bottles and not training cups. thx btw
