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, imagination-expanding art classes, and Gymboree's most popular class, Play & Learn. The one-month membership allows you to take one class per week, with makeups available during enrollment if you miss a class. This deal also includes unlimited attendance at Gymboree's open-gym sessions (contact location for schedule). 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 classes help build an everlasting bond between parent and child that will feel like being tethered to each other with Ethernet cable.
