Aww....cool! Ann Arbor is alright. I do, however, like the lamaze center here. They offer a really good postpartum/baby class and then they continue on for your baby's age. There is also first steps of washtenaw that has cool baby classes... They even work on a sliding fee scale, which is great because I live off a grad student stipend..lol!
edit to add: AA is nice...I just got used to San Francisco...my husband and I moved here for school at UM...
