He is 3y4m. After many false starts, he's been toilet trained since early June - early June was when he started realising he needed to go, and mid June was the first time we were out and he told me he needed a poo.
He seemed to get it really quickly, probably because of his age, and barring the odd few accidents when he was tired or very grumpy we'd had no problems.
Until a week ago. He came back from nursery and had 2 accidents before bedtime. We just assumed he was tired, but that has continued ever since. He is now completely not using the toilet at home, unless we prompt him, which we only do before bed or if we're about to go out. When he's out and about he's fine as usual, we probably prompt him more but there have been times while out that he's told us.
What on earth is going on?
