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

i recently trained my 3 year old to sleep without a diaper at night. here are a few tips that can help: 1. reduce the amount of liquid intake from the evening, especially an hour or so before bedtime. 2. take baby to the washroom and help pass urine. 3. gently pick up baby 2 to 3 times in the middle of the night and help pass urine in the bathroom. it will take a few weeks at the most, but your baby's body will soon get tuned to the routine. very soon, your baby will be able to wake up in the night and ask to go to the washroom.
