How do I stop my 3 year old from bed wetting?

Before going to bed, do not make her drink milk or too much water. If she takes milk before going to bed, make sure, she has had it atleast one or two hours prior going to sleep. You can make her pee at least once at night. My daughter is 6 and just a few months back she stopped bed-wetting. I take her to pee say around 3 or something in the night, and now, she herself wakes me up for it. So, kids do adjust. Try doing these things and soon she will become habitual and will herself wake you up whenever she has to pee even during the night sleep.
