DD 4yrs is desperate to be dry at night but she isn't there yet. She's now refusing to wear pull-ups at night so I've tried out the bed mats. We put them under the sheet as they slide about and also she doesn't like them on top which means I'm changing the sheet every day. Her duvet cover also seems to be picking up some wee so I'm going to have to buy a protector for that. Should I make her wear the pull-ups or should I persevere with the mats? I keep hoping that she'll soon be dry but I know there's no telling how long that'll take!
