The books/forums I have read talk about watching out for the warning signs your child is going to have a wee, and then rush him to the potty. DS is 2.9yrs and this is the third time I have given up potty training. He is happy wearing pants, can pull them up and down, knows when he is having a wee, but you can be talking to him and him just suddenly wees, with no apparent sign that he knew it was coming. Other times he will (seemingly randomly) ask for a cuddle in a fairly urgent way, as if he feels like a wee is coming, but then another hour will pass before he actually has the wee. He doesn't as a rule drink much (and you can't force it down him) and for the past two days has only had two wees each day, he is ok sitting on the potty but surely all the advice of the books is useless when we don't see any warning signs of impending wee at all!
