My daughter is having complaints of pulling up of mouth to one side.This doesn't happens every time but only for certain words.otherwise she doesn't have any problem.achieved all Mile stones as per age also.i m not sure that whether she is doing ths purposely or does she got any other problem.one more thing I wanted to add is that she is very much dependent on mobile screen.she sees cartoons late nightly,does ths habit got any relation with the facial deviation?
