They want me to sign a form just for Grayson since she has CF. I would prefer not to sign anything. I wouldn't hold them liable if she would get sick. I think i may try it out tonight since her sisters will be in the room prior to their dance class. Both of my older girls are very aware of what is safe for grayson. My husband watches her a few nites a week to i can do some running. But not all my other kids activities are at the ymca. We have gymnastics at another place, and girl scouts at another. So most of my free time would be during the morning/day time.
