There is a great mom and baby yoga class at Namaste Yoga in Royal Oak on Tuesday mornings. Also, local libraries usually have (free) activities for moms and babies/toddlers. I know that the Royal Oak library has at least one per week. I've met so many friends that way! Also, go to the Detroit Zoo on any weekday, now that it's nice, and you're bound to meet someone. Good luck!
