DS aged almost 4 has been completely dry in the day for 8 months and at night for 2 months. During this time he's had no accidents. He will happily use the toilet while anywhere and everywhere while out, but only for wees. At home during the day he will only use a potty. I know this must be laziness because of him using the toilet elsewhere.
I removed the potty completely a few weeks ago and he agreed he would now use the toilet. We have just the one toilet which is upstairs so he would wait until the last minute and leg it upstairs just in time.
The problem also is that he refused to poo. He held it for a couple of days and then started complaining of tummy ache. I relented and got the potty back out, I couldn't stand the thought of him withholding his poo.
He stayed with his grandparents for a couple of days last week and during that time didn't poo, he saved it for his potty when he got home.
What should I do about this? Do I make him go cold turkey and bin the potty? Shall I resort to bribery, extra present from Santa? Or is it not worth worrying about and something that he will do himself in his own time?
