C.,
Welcome to Michigan! I work for a global relocation company and always give this information to my clients. You might want to check out the websites below. The newcomers club and moms & more are great ways to meet new people. Also the library has great mom and child activities. RARA is the Rochester Avon Recreation Authority. They have tons of activities for kids.
Good Luck,
S.
