One thing that does have me worried is she moves is a very odd way , like she twirls a lot when moving which I pretty sure isn't normal. It's been going on for a while , not that it's impairing her from moving or anything she just falls from time to time and half her body may twist when moving and then she realigns herself a second later. Is the because of a vitamin deficiency ? and how long would it take to fix this issue ?
