DS is 29 months old and this is second time of attempting potty training, the first being 3 months ago. Basically after three days we are still getting a lot of accidents - the problem being that he is great at weeing when put on the potty but won't go himself so if he needs one he just does it! Also he doesn't seem to go very long between wees, which means he isn't actually holding it in for any length of time - no longer than an hour or 1.5 hrs. Is this something that he will 'get' if I carry on with the training or do I need to go back to nappies? (My Mum looks after him one day a week and refuses to change a 2.5 year olds nappy.... Hence the training now).
