T.C.
I usually go on Wednesdays with (or without if we're running late) a small group from Holy Cross parish over to the Enoch Pratt library on Light St (if you're somewhere toward the south of Baltimore) close to West St (where Holy Cross is) for a preschool library time at 11 am which is great- they do a mother goose hour (half hour?) before that at around 10 am for smaller ones- and i recently grabbed a copy there of Baltimore Child which lists a lot of storytime/ sing-a-long groups in batlimore- and the YMCA used to have a mommy/baby or daddy/baby swim class- hope that helps
