Dd has been potty trained for a few months, but for the last month or so we've had about 3 lots of damp pants a day. Like a little bit of wee leaks out and then she says she needs to wee. It's enough to have to change her pants (and sometimes trousers) but never more than that. Is this normal, and something she'll just grow out of if we don't make a fuss? There's no signs of any uti or anything like that.
