My DS is 3.6 and has resisted all attempts at potty training until very recently. In the past week he has been using the potty for wees if he's naked from the waist down, although still with quite a few accidents. Today we were playing upstairs when he was bare-bottomed and I'd put a potty out and made sure he knew where it was. I nipped away to get my DD from her nap and came back to find him standing on our bed doing a wee. Before I could stop myself I yelled at him to stop and he got quite upset. Later when we suggested he use the potty he became really distressed although he did sit on it eventually, but he didn't do anything. I feel so bad and I'm worried I've undone months of gentle cajoling in one fell swoop.
Can anyone advise what I should do next? Can I press on or do I need to back off for a bit? Thanks
