My 10 month old fell off bed that is a lil over 2 ft tall, when I got to her she was on her tummy crying, her neck was red but she seems to,move her neck both directions, there was a small red mark on,her upper back close to neck.it has now been an hour and a half and red is,gone, she was crawling and acting fine before her nap, she is sleeping now, should I,be concerned that she hurt her neck,or back
