Oh gosh Kindergarten is the best age ever! I love when they are so proud and want to read to you or whatnot. Omg<3 I also observed a Kindergarten class a year and a half ago, and I absolutely loved them. They were excited when I came in on Friday mornings, and I would stay until lunch time. The kids always wanted me to sit by them during their morning message time.
Oh and I know what you mean, I worked with 2 year olds at a daycare. Never. Again. I hate the daycare setting anyways, because I've had bad experiences with the ones I was at. I like the SCHOOL setting a lot better [preschool and primary].
