DS is 3. He was potty trained at 2y3m and did well until his brother was born 6 months ago. Then the regression from hell hit and after 4 months of wet trousers (upwards of 5 accidents per day), we took a step back and put DS in nappies again and just forgot the whole toilet thing.
2 weeks ago, we decided that it was time, as DS is 3 this month and is obviously capable because he did it in August. It is exactly the same as before.
I set a timer and take him to the toilet every 30 minutes without fail. He does a wee (however small) every single time. Yesterday we had 5 large accidents. It's 9am and we've already had an accident today.
When he has an accident, he could not care less. I make him change out of his wet clothes by himself and put them in the wash. I give praise when he stays dry. I remind him to use the toilet when he needs a wee after he's had an accident.
Where am I going wrong? I don't know why this is so difficult because he absolutely understands what needs to happen.
Please help!
