She has been dry at night since she was four but has wet the bed three times during the last five nights. Not just a dribble, but absolutely soaking the mattress. She has a big wee before bed and I've tried cutting down on fluid after about 6pm. She doesn't seem particularly stressed about anything much, she's a very laid back child, although she has mentioned a recurrent nightmare but she can't remember what it was about.
Any other ideas or could it be a urine infection? She's not sore.
