My DS1 was toilet trained at 2.2yrs. It took ages but he got there in the end (by age 3). For a long time he was totally dry (though has never been dry at night yet). In the past few months, he has started having wee wee accidents again, once or twice a day. Sometimes it's a bit in his pants and trousers and he then makes it to the toilet. Occasionally, it is the full amount! I've no idea why he has started doing this again. He seems to 'forget' until it is too late, or is so engrossed in what he is doing that he doesn't notice until it is too late, or sometimes I think he just can't be bothered.
I've tried telling him off along the lines of 'your a big boy now, and big boys don't do that', but it's not registering. He starts school in September.
I'm hoping that when he gets to school, this will stop. Any experience/advice?
