kind of weird about the potty training...unless it is a paid for daycare, I would think your child would need to be trained.
I am 34, born and raised in FL....Nov bd, I started school at 4 in K and graduated at 17. Now the guidelines have changed....age 5 by 9/1 and yes, I'm sure potty trained. DD is a halloween bd so, while she was ready, she had to wait it out. My other dd will be 5 in Feb so no worries....what gets me, there is a child in my dd's school that is her age but will be 5 in Aug as opposed to Feb.....she is the youngest of 3, the eldest sibling is my other daughters age and they grew up together and are in the same grade. etc. and yes, I know it is up to the parents, they know best , etc...but these parents have already decided she will not being going to K next Aug, so much so, they did not let her move up to the next daycare class (which is the last before K).......so here is a young girl who's parents feel she doesn't have enough leadership qualities to move ahead yet, stuck in a class of newly potty trained children and is in fact regressing....really makes me sad.
I guess there would always be a point to hold a child back, but why start them out that way?
