hey, my two boys go to a preschool (private) and they change anything from nappies to undies, and rinse the undies before putting them in a plastic bag for you to take home. everything is written down for the parents.
but i think says tht yur child can not go to preschool, kindy or anthing like that because they are not toliet trained is discrimanation (sp) do they reject children for disabilitys? every child learns at their own pace. if i was you i would go in and tell them its not fair to do this to a child, its not like they know better.
well thats my two cents anyways... good luck
