Safety is our first priority, so we do not allow kids to be out of the stroller during class, regardless of age. We offer exceptions for moms with more than 2 children when she does not have a stroller/wagon seat for her older child(ren). Contact us at noco@fit4mom.com to request a "big kid waiver." These requests are approved on a case-by-case basis. Thank you for helping us keep all the mamas and little ones safe!
