She is quite lean. And i can see one small prominently in the middle of her back along with the spine. It doesn’t hurt her. But i wanted to check if this is normal for her age. This is not lump or any other health related issue right?

A. It is the bone positioning like this it seems completely normal to me and yes it is not looking like a lump as you mentioned but if you need to be more sure about it you can just consult orthopedic assessment done to be more clear about the situation
