My son is in Kindergarten this year. He did go to a 4K program last year which is 4 days a week half days. He's usually a really happy kid but now after school most days he's a bear to handle, because the days are so long, I'm sure. He's also started sucking on his fingers. He's never been a thumb sucker and now he's almost always go either his thumb, pointer or pointer and middle fingers in his mouth. He's also started peeing his pants everyday at last recess. Anyone have any thoughts on this?
