the child care




+ Our child care facilities allow children ages 3 mo. to 16 years. Any child younger or older than the specified ages should have other accommodations outside of the studio.  

+  Children must not be left alone in the studio or lobby space without proper supervision, as the machines pose a liability to the child and to Fierce45. 

+ Children under the age of 3 mo. are permitted to be in the studio space with an accompanying parent, as long as they are in a car seat and out of harm's way.  Parents choosing this option must accept full liability for their child(ren) in case of accident or injury in the studio space.

+ Each child must be signed up and paid for individually before entry to the studio.
