I shudder over the very thought of trampolines. My oldest went to a neighbors house, back when he was 9. He and his buddy were on one of those huge ones in the backyard. DS was coming down and his friend was coming up and hit DS right under the jaw...his teeth went right through his tongue. Folks...if you ever had to get stitches, this is like the last place you want them-no less to watch your kid get them there. DS nearly bit his tongue right in half-it was hanging by a thread. It was a blood bath and thankfully DH was home to keep it together, because when your 9 year old comes in covered in blood and his tongue hanging out and by a thread (sorry to be graphic), you kinda lose it as a mother. I haven't let any of my kids even THINK of going near a trampoline since then. If you must get one, please exercise extreme caution-even then accidents are very high on these things. I could have sued the neighbor, but we are not the type. Our medical covered son minus a $50 ER copay, but it was a highly traumatic thing for everyone.
