my 11/2 month old grand child has a glassy eyed stare. Makes him look as if he is not seeing, or just very mellow and saintly. His sister always had old grownn-up knowing eyes from day one.. how can there be so much difference? My son , his father , never had glassy eyes, nor anyone else in my family. what does it mean? He is so serene and mellow that I have named him the next Pope!! Is he seeing anything.? He should be distinquishing forms at this stage, no????? Curious, almost concerned grandmother.
