Gymboree offers a bevy of baby-engaging classes, in which parents and wee ones work together to build tots' creativity and encourage development through play. Weekly classes are available for every age from the freshly born sapling to the 5-years-young wise wanderer. This deal includes rhythm-building music classes, sports classes, imagination-expanding art classes, and Gymboree's most popular class, Play & Learn. The month-long membership allows you to take one class per week, with make-ups available during enrollment if you miss a class.

Independent of today's deal, most area Gymboree locations are currently offering a $50 membership gift certificate until the end of February. However, this Groupon is valid through June 2, 2011 and also includes a waived initiation fee, making today's deal the better value. One Groupon must be purchased for each child, and each child must be accompanied by at least one adult (but more than one adult is welcome). The 45-minute classes help to build an everlasting bond that will feel like being tethered to each other with ethernet cable. Bond with your baby or exercise childlike energy in a public forum with today's Groupon to Gymboree.

This deal is not valid for birthday parties, toys, or school skills classes. Valid for new families.

• It is a safe and clean environment for kids to play in, and the materials used during play time help to develop motor skills. – Janisha L.
• This is as good as it gets. It feels good when you walk in the door. No fuss, nothing pretentious, just a great area for kids to play, nice toys, and great, friendly, talented staff. We love it. – John M.
