I'm looking to start a Niche Gym for Parents & Kids. Feedback?

I am not a parent, but I have been a personal trainer as well as worked for gyms that are close to this concept. I really think you have something going here. Most gyms with child care have a wall and the children and parents cannot see each other. The only barrier you may find is for younger children with separation anxiety. Seeing their parents on the other side could make that worse, and the parents may not use your gym because of it. Otherwise....I think it's great, and definitely sets a good precedent for children to see their parents working out, and the opportunity to give them something active to do. They'll have fun and won't have a tv;)
