Hi my tall 6 year old has a strange shaped rib cage. I noticed it over the last 6 months. Compared to my sons it really sticks out one side to the front then the other side is much lower . I really notice it when I put my hand on her chest. She is rather skinny so I guess I notice it a lot. My sister has scoliosis so I bit concerned. DD has a straight back bone. I will take her to the doctors but just wondered if anyone else's children have wonky shaped chests?
