Query: Entertaining With Exercise

My two daughters (ages 4 & 2 1/2) thoroughly enjoy their new indoor/outdoor trampoline. It seems to be very sturdy, and it wasn't too difficult or time consuming to assemble. I was inspired to purchase a trampoline after I saw how much my 2 1/2 year old enjoyed jumping on one at her Tumble Tots class. I do fear that it may eventually fall forward when they jump, but knock on wood, it hasn't happened. My kids like to swing from the bar, but I try to discourage that immediately. The only real problem we've had with the trampoline is the sharing factor. You know how kids can be? Regardless, it is instant entertainment with just the right amount of exercise for your little one.
