My DS2 will be 3 in January and we are having a bit of a struggle with potty training. He is brilliant with his poos, I would say 99% of them go on the potty or toilet. Wees on the other hand are a bit more tricky. If we are at home with nothing on his bottom half he is pretty good at knowing when he needs to go, and just goes straight for the potty and wees on it. If he has anything on, pants, pull up, or just commando under trousers, he just pees in it! We have tried setting timers to sit on the potty every 30 mins, sticker charts, rewards etc but as soon as he is covered up he just wees in whatever he is wearing. Any wise MN advice?
