My child looks sideways when watching tv

Is there some medical answer to this. I tried to correct her but often caught her doing it again. My brother in law said he was like that when he was a child and later on just corrected it himself. He do have a photographic memory. Should I be concerned about my daughter? I see noproblem in her behavior other than this.

Sorry to bother you, but i was wondering what you ever found out with your daughter's vision.  My son is doing the same thing and i wondered if i should be concerned.  Thanks!!

hi, is this obvious just in watching TV or other activities specially fine skills are done in the same manner?
how is his fine coordination? if it is observed in other activities it seems to be due to diplopia. any way a vision specialist should visit your child in my idea for more confidence.
