HI Carrie, I was the same as you and had my 3 1/2 year old in a in-home daycare, mostly due to my fear of all the germs & flu in daycare centers. But last May things when kind of bad at our in-home care and I had to search for plan B. So, starting in August my oldest started a pre-school program, she was 3 years & 4 months when she started and that was perfect timing. She was also the oldest in her in-home care and she really needed more activities. Her pre-school program is great. I also work full time so she is there m-f 8-4:30, they have an aftercare program. She has "started" to spell & write her name, and learned almost all of her abc, in just the first few months (she knew her abc, but couldn't always point out the written letters, now she can!), and they due a ton of sensery activies that the kids love. I also love going to the class room and seeing all the pictures and things they have made! I am almost glad things when bad at her in-home care as it moviated me to make this change that has been for the better. I also accepted the fact that germs are everywhere and she can get sick from the grocery cart at target. Also her pre-school has been very proactive with the flu season this year, extra cleanings/clorox wipe, etc..
I do have my 1 year old at a home with a lady we love, but I think 3 years is a great age to get in pre-school. My daughters school requires you to be 3 before August 1st, for their "3yr" program. Her class is actually a mixed class with 3 yrs & 4 yr olds, which has been great for her interacting with a little older kidos. Good luck, I don't know anyting about the kiddie kollege, but I think a pre-school program is a great idea! Oh ya, I also love hearing all her storys about her new friends when she gets home.. so cute!
