ANY JUMPER IS TERRIBLE FOR YOUR BABY'S SPINE! YOU MIGHT NOT SEE THE INJURY NOW, BUT WHEN THEY ARE OLDER THEY WILL FEEL THE EFFECTS! THESE AWFUL DEVICES ACTUALLY COMPRESS VERTEBRAE FROM THE FORCE OF THE JUMP...A BABY'S BODY IS NOT MEANT TO TAKE THIS TYPE OF FORCE. WHY WOULD YOU INTENTIONALLY HARM YOUR CHILD?!? IF YOU PURCHASE ANY TYPE OF JUMPER PLAN FOR A LOT OF TRIPS TO THE CHIROPRACTOR IN THE FUTURE FOR YOUR CHILD!
