full control but refusing potty

[LaSchtroumpfette]

My 2.9 years old toddler son was physically fully ready for PT since he was 2.0, but I did not have time or energy for PT untill last month. Then we started with a quite soft approach but now realised that we have a big problem. My toddler is out of nappy all day and night now almost no accidents (only one night time accident) but he wants us to put him in nappy when he needs to go rather than doing it in a potty or toilet. He refuses potty or toilet. He is happy to pee in the tub but not in a potty. Current situation is: he tells us when he needs to pee or poo and we put him in nappy and take it off as soon as he finishes. Of course this can not go like this, I don't know what to do now. Really need some advice.

Have you thought about trying him on the toilet rather than a potty? You could take him out to buy him his own special loo seat and stool and give him lots of encouragement etc etc. Either that or take the harsh line and just remove all nappies from the house so he doesn't have the option.

Get rid of the nappies. He is quite able to do without them. Why not ask him to choose what he would like to use instead, potty or toilet. Rope in little friends who are happy to sit on both to demonstrate that nothing bad happens when they do.

My 2.10 year old dd is exactly the same at the moment. I'm finding it so frustrating!! Today and yesterday she went for 2/3 hours with knickers on and no wee but refusing to sit on the potty. The second I put her nappy on again she had filled it. I hope this means she has some bladder control but have no idea how we get past her hating the potty

She did a poo in the potty a few months ago and was really upset when she saw it in there. Her fear started after this I think?

another option -
day 1 - let him poo in a nappy, but only if sitting on the potty at the same time
day 2 - put the potty in the nappy, then sit him down on it and get him to poo.
day 3 - swap nappy for some toilet roll in the potty
worth a try!

Thanks for the answers ladies. Unfitmummy, I tried putting nappy in the potty, didn't work. He insists on having the nappy on.
Mintyfresh, I think they are anxious about something. Last summer when he had a nappy rash I didn't put him in nappy few times and he had a couple of accidents. Unfortunately my histerical MIL was around and she screamed each time he accidentally did it on the floor. I remember the panick in his eyes when that stupid woman was screaming in hysteria (I'm really angry with her) and i think he is still anxious about doing it somewhere else except nappy.
Heth1980, we did try tiolet, there is no difference.
Our problem is still continuing and I'm trying more relaxed approach now and doing whatever he wants to do. I don't know whether this is a mistake.

No other ideas??
