I would be more than happy to look for some info on preschools for you. I am a stay home mom also of a 7yr, 6yr and 2 1/2. I am also a Real estate agent but i work from home, am i still a SAHM? anyway i live in Oxford but am with Real estate one in Rochester. You are going to love Rochester. I know of two preschools...st john lutheran church. I also believe Kennsington Church also has a pre-school. You need to check out thier web site. It is in Troy, awesome place. I do not know where you are moving from but be prepared that child care is on the expensive side.
As far as obgyn i do not know off of the top of my head who to recomend, we moved her 1 1/2 years ago and i have been poorly neg, on finding one for myself.
I don't know if you have found a home yet but i would love to help you with that also.
Please feel free to call me. my cell phone is ###-###-####.
I am also with MOPS in Oxford so maybe between that and kennington i can offer some good advice.
Hope to hear from you,
C.
