My cousin's body structure have been a source of concern for her parents since conception.

When she was around three, her neck was like twisted and leaned one side but wasn't that noticeable, but now she is seven, her walking issue now affected because of her neck. She can't walk upright, she can't run, she can't bend with ease and she seems to develop this super flexibility on her legs when she sits on the floor, her legs can stretch to the back and looks like there are no restrictions.

The bones in her body are super soft and frail, she can't squeeze things at all.

My uncle has been disturbed a great deal by these and have been going from place to place searching for solution but none seem to avail.

Doctors in the house what can you say is wrong with my cousin sister.

Osteogenesis Imperfecta

Pictures are the only sure way of knowing how to diagnose the case.
