I trained my son last year, when he was 3. I deliberately left it to when I thought he was ready and the whole process took a couple of weeks - from potty to toilet. He still had accidents at nursery, but never at home. He is now nearly 3 yrs 8 months and has recently been getting on much better at nursery, but has just started wetting himself with me this week. He had 3 accidents yesterday. I have tried to just be calm, but admit that I have lost my cool with him which I know is the wrong thing to do - and feel very guilty about it too. It's just so frustrating having to go through this again, and not knowing a reason for it and made worse when your child doesn't seem to care and would happily sit in soaking clothes all day.I've read lots of explainations and have been trying to work out why. He's been happily going on his own for the past few weeks at home, but at nursery I know they take him every half an hour. Could it be that he's got used to being prompted and got lazy with reading his own body? I have just started back working 2 days a week, when my mum looks after him and my 1 yr old son, but he's very happy with her. Has anyone else had this experience and what did you find successful?
