Not sure if title explains it well. DS now 3.6 was abit late in potty training 3.2 for wees (he then went from nappies to being totally dry without accidents in a couple of days), it took him longer to get the hang of poos but he seems to be about there now with the odd accident.
Anyway sometimes if theres something he doesn't want to do, he'll say a need a wee-wee or i need a poo-poo so he can go to toilet potty. Like yesterday for example he didn't want to go to nursery (specific reason for this now sorted) so when we were out at car he says 'i want to poo-poo' so i asked him if he really did and that i would be cross if he wasn't telling the truth and we ended up going back in and then he did a massive poo so he was telling the truth. But then this morning he was messing around and didn't want to get dressed so he said he needed a poo and then went and sat on potty for about half hour with no result. If he ever gets put on naughty step he instantly needs a wee
