Toilet training..... need some advice
...... ok so Oskar will be 3 in March and does wees in the toilet and has been fine with this for quite a while now, but not poos - these are in the nappy. Over the past couple of weeks though, he's decided more and more that he wants to wear undies during the day, in fact it's every day now really. He doesn't have accidents. One day he did do a little poo (about 2 wks ago?) in his undies and I cleaned it out for him and just reminded him he had undies on and that if he wanted to do poos it was in the toilet or nappy.
So, he used to do 2 or 3 poos a day but now he'll go a day or 2 without doing one because it seems he doesn't want to do them in the toilet BUT he doesn't really want to do them in his nappy either! He did one poo in the toilet about a week or week and a half ago but won't do it again. Have tried offering chocolate if he does one and even have a special present for him which he knows about for when he does a poo in the toilet.
What do I do?? He will tell me he has a sore tummy or a sore bottom and he knows he needs to poo but he's holding it in. He's not constipated. I'll ask him if he wants to go and do poos on the toilet and he says no, do you want a nappy on, no.... then eventually he will say yes to the nappy (this may be a day later though) and do a poo almost immediately! What other suggestions are there? I do worry that he's not pooing enough as he used to be so regular and now he's making his tummy and bottom sore by not going!
