B.M.
There are music classes offered on the weekend (both Saturday and Sunday) in the Plainfield and Naperville areas. They are called Music Together, and are wonderful! I've been taking my daughter since she was 8 months old (she is now 2 and a half). There is a December sing along class starting just after Thanksgiving that will be running for 3 weeks, and their Winter semester starts in January. Go to www.musictogetherofnaperville.com to check it out, and you can even schedule a free demo class if you want to check it out before you commit. We LOVE it, plus its a great way to meet other moms!
