#asktheexpert my son 2year old have been always saying to me that he has a pain near his hip ... I guess this is because he used to jump and fall on bed .. he used to jump and lift both his leg and sits down on bed... on day he did the same and slept on his back and he felt some pain ... and from that day he has stopped jumping like that.... and from that day whenever he feel the pain over his back he tells me mamma my back is pain
