Hi M.,
I have a 2 and a half year old daughter also, and she just started a 2 day a week "preschool." She is doing well, although we have had crying and still some reluctance on school mornings. However, she has only been with me to this point, so this is new for her. I am an educator, and I say that the earlier you introduce your child to "formal" education, the better. If your home day care is also child care (as in, you have to go to work), you may want to leave your child there until age 3, if you are happy and your child is happy there. If your home day care is more for your child's enrichment and your peace of mind, you may want to try a preschool. Most of them run in line with the regular school year, so they may have already begun for the year,but you still might get in. My older daughter was in "school" from the time she was 13 weeks old, since I had to go back to work at that time, and she did SO well. We shopped around for a great school for her, and she thrived. Anyway,, this is just one opinion! Let me know if you have other questions.
