we started PT yesterday and my son has yet to get in the potty (lots of clean up), BUT he's gotten much better at holding. The first 2 hours, he must of peed about 4 times and by the end of the day, he had his legs together holding it in so I guess that's improvement in terms of having more control of his bladder. We are going to give it through Monday and if he's still not getting it, then I think we will postpone until winter holiday when my son turns 3.....I know boys are delayed in general but the only pressure we really have is for the American School in August 2011 who says your child must be potty trained for pre-school.
