Little grasshopper, I am sorry to hear about your accident with the ball. So how are you now? Fully recovered? If that had been me, my husband would have made me pop the ball.. ah.. wait.. he would have popped it himself no questions asked.
When I first bought it, I read some posts about small children always wanting to play with it and didn't see why that was a problem.. then my own children (18 and 21) started "playing" with it.. yup.. I now know the problem! The youngest actually stood upright on it! I couldn't even say anything I was so shocked. If he had fallen over he would have gone right through the glass doors.
I use the ball in a room that has a lot of space and not much of anything else. I've come to really come to like the workouts and feel comfortable with the ball. ... unless of course my son decides to get it out to sit on while he watches tv..
When he goes away to college, I won't worry about this house not being "child proof".
