We had an issue with my daughter staying dry at night and figured it was the juice at bedtime, so we began to institute the "swallow" before bed. Instead of leaving the full glass of juice or water in her room at night, she got her "swallow" before bed and she seemed fine with it. She slept all night and didn't really mind not having the whole glass there. She usually downed the whole thing before going to sleep anyway. Also, we began to suspect that the times she woke up wet, she likely wet her pull up AFTER waking up, because she was sleepy and warm and didn't feel like getting up! Once the pull ups were replaced with big girl underwear at night, she never had an issue again. That said, my older daughter didn't stay dry at night until she was about 6 or 7. This is also normal and shouldn't be cause for concern. Many children have this issue due to the part of their brain that wakes them up from a sound sleep to tell them to go to the bathroom not being mature until later. My dr. said that this was likely hereditary and one of us also had this issue. I blame my husband! LOL! Anyway, we just had her wear pull ups at night and when it became important to her to learn to stay dry at night, about the time she started to get invited to sleep overs, we used an alarm in her undies that woke her when she began to pee. After about a month, she was cured, mostly. I think she still had occasional small accidents for a while, but for the most part, she was good. If this is the case, we were strongly advised to not make a big deal out of it. Don't punish or yell or make them change their own sheets or whatever. It just makes them feel worse about something they truly have no control over. If they could stop, they would. Hopefully you will not have this issue, but I threw it in just in case! Good luck!
