DS1 has been potty trained for wees for coming up a year now. We've never (well apart from once a year ago) managed to get him to poo in a potty. He is quite easy to understand, and knows exactly what is going on, but refuses to even think about pooing in the toilet. If he knows a poo is coming, and he is naked for some reason, he asks for a nappy on. If he's wearing pants, he'll just poo in them. We have tried all manner of bribes, and our answer to anything that he wants (he wants every toy he sees an advert for!) is not until you do a poo on the toilet. If it ever happens he'll bankrupt us if he remembers everything we've promised him! The last couple of times he's said that a poo is coming and asked for a nappy, I've persuaded him to sit on the toilet, but he's just held it in.
Any words of wisdom, or do I just wait? It's OK when he's in a routine of just doing a poo at night time, but he's just getting over a tummy bug, and pooing at all times of the day, so I've had to resort to putting him back in pull ups when we're out of the house. Not ideal, as then he won't go to the loo when he needs a wee.
