Hi, I'm having problems getting my ds,(who was 3 a month ago), to use a potty. He's very tall for his age, so have bought a potty chair from Mothercare. He will wee on it, but will poo on the floor next to it (if not in his pants). He can tell you that he's meant to wee and poo in the potty, but I can't get him to poo there! I've tried to get him to use the toilet too, but he cries if I ask him to do anything. The local nurseries/playgroups won't take him if he's in nappies. My dd is 2, and she'll be trained before him at this rate!
