My dd is 2.9 and wants to wear pants like her friend but when i take off her nappy she will hold her bladder for well over 3 hours then massive wee on the floor. She is then upset that her clothes are wet and comes to tell me staright away. (The same with poos) But she won't tell me before. She will sit on the potty or loo and try to squeeze something out but says it doesn't work. When ever i put a nappy back on she wees straight away. Do i keep trying, am worried she'll end up with bladder infection from constantly holding it in.
