Hi! So funny that you posted that! My little one does the same thing, zoning out to the point that we have to wave a hand in front of his eyes and say HELLLOOOO. I think for the most part it is normal and may be just from a being stimulated or sleepy. But you may want to mention it to your doc... When a baby is having a petite mal seizure, it looks like they are just zoning out for some time. I am sure that is not the case, but I just thought I'd mention it. (Now I need to follow my own advice and mention it to Nathan's doctor!)
