Baby's can have cataracts sometimes. I would call tomorrow to an opthomalogist and have her seen immediately. We used Simpson Eye clinic and they are awesome. They have a ped. opth. there too- Dr Turoc, but you may have to travel some to see him- he stays booked.
I would not let it go- it may be nothing, but it could be something really serious too, so definitely get it checked ASAP!
