My ds is 2.5 and a couple of days ago asked to use the potty and did a pee and a poo. Decided to give potty training a try and it was going fairly well. Except tonight after I put him in his nappy for bed (no way he's ready for overnight training!) he did a tiny wee in his nappy and was inconsolable. Kept asking to use the toilet so I let him and he didn't do anything. He seems terrified of going in his nappy and keeps crying and saying "no pee in nappy, I'm a big boy". I'm so worried he's getting so upset about it- we've made no issues when he's had an accident and told him it's ok to pee in his nappy at night but he just keeps crying and saying it's not ok! My heart is breaking for him and I don't know what to do. He's nowhere near ready not to wear a nappy at night but he's getting so upset. He wants to sit on the toilet all the time in case he has an accident! Please help!
