My DS is 3 and a half, and has been potty trained and clean day and night for around a year now. He was very lazy telling me he needed a poo when we first started potty training, but has been fine for ages now. However, yesterday and today he has had 8 poo incidents, where a little blob of poo has come out. It's not runny, or even that soft, just normal. He is absolutely fine in health apart from that too. What's going on? I'm really puzzled. It's like he doesn't know he needs to go?
