L.C.
I've worked at 2 child care centers and I've also been a nanny for 3 families.
If I were in this situation with my own child, I would choose a nanny 100%! I could list so many reasons why, but I think stability and consistency are two of the most important. The teacher turnover rate at child care centers is very high. I really feel the next best thing to having a SAHM would be to have a good nanny.
If you would still like your child to be exposed to other children, you can set-up weekly guidelines for your nanny. Have her take your child to a playgroup or class once a week and to the park another day.
If you decide on a nanny make sure to do a background check and check her driving record. Macomb Community College & Rochester College both have Early Childhood Education Programs. These would be a great places to post a nanny position flyer.
Let me know if you are interested, I know the ECH Education director at Macomb CC and I can give you her name.
