The Yoga Center of Columbia offers a baby and me yoga class on Mondays at 11:15am. It looks like fun. Call to schedule an appointment (410) 720-4340. Just wear comfortable clothing and bring a receiving blanket for the baby. It’s a very interactive parent/baby class. It’s $20 to drop in for 1 class, and $176 for the 11 week session. You may also sign up for less than the full session by paying $18 x the number of classes.
