I have been the SAHM from day one, and my son will be entering full day preschool in the fall. He will be four in January. I am cautiously optimistic about the transition from home to school, especially so early in his schooling career. The structured aspect of school will be six hours (1-1.5 hour nap included), and he will participate in the after-school program (play daycare) for an hour a day. The school's reading program focuses on the fine motor skills for writing letters, rhyming, and letter/sound correspondence. Math is writing numbers, counting and comparisons. The class has calendar, story time and a lot of play time. We do all of these at home, so I want to make it clear that we aren't sending him to preschool so he can get the edge up on the competition. I felt that this school would continue the pace and concepts that I have with him. I can admit how we had selfish reasons for sending him so early. I student teach this fall and finish my teaching cert in December. We are fortunate that our son is social, bright and excited about the school opportunity. Additionally, we met the teachers, and I picked the one that seemed to reflect my style the most.
The structure is going to be the biggest adjustment for him, I believe. He seemed to do well two weeks ago at my friend's in-home daycare, while I recovered from surgery. He napped at her home (he never napped away from me, daddy or grandma). He followed her rules and directions. He had a little trouble with the food schedule since he's used to eating snacks whenever he's hungry, but he and I talked about what to do about that after the first day (i.e. ask her for something to eat).
Another concern that I had related to communicating our values. We want our son to have manners, be honest, tolerate differences, etc. If I'm not there, how can I know that he's getting the appropriate coaching? Now that he's able to talk with us about things, we know that he will tell us what happened. He knows how we feel about certain things. A hot spot for us is that our friends are gay parents. We talk about this sometimes, and I wanted to know how the teacher/school would react to my son saying that two girls can get married. I found out and was pleased with the response.
It's a personal decision and requires you to inventory your child's strengths and weaknesses with this kind of transition. Good luck!
