Yes, they charge adults. Depending on the little girl's age, it may or may not be worth it. There are a lot of interactive exhibits that require adult participation and/or supervision. While they do have volunteers walking around, it's not a place where you can let the child totally roam free unless they are older.
Your question needs a bit of clarification. This is not a gym that is equipment based; this is a museum/play arena for kids, with exhibits to engage and play with. So, if adults want to get in, yes, you have to pay. Now to your mom. She can still sit within a watching distance of the kid but outside the perimeter of Mobius play area itself (you'll know what I'm talking about once you reach there). This place is not like a swimming club where adults can come in for simply "watching" or "supervising." You come in with your kids and pay for all, or you sit outside while your kids play inside.
Hi Amy, Mobius Children's Museum is a place where parents/guardians have the opportunity to engage in hands-on learning and exploration with their children. Just to clarify the other comments, children are not allowed to be on the exhibit floor without a paying adult with them (you're not able to watch from "outside the perimeter"). Our daily admission covers an entire day of hands-on learning and fun! Mobius is a nonprofit organization that relies on daily admission, memberships, and donations to continue to providing education experiences to our community. We hope to see you soon! Please let us know if you have any other questions.
