Hi Everyone. My little boy has just turned 4. He's been potty trained for a while now. However at night he still has to wear a nappy as otherwise he'll wet the bed. He doesn't even wake up when he does. So my question is: do I have to wait for him to have a dry nappy every morning for a certain amount of time and then take the nappy away? Or should I encourage him to become dry at night? He has woken up before in the night to use the toilet but that happens very rarely. He's a very deep sleeper. Any advice would be appreciated. Thank you ! Xx
