hey, my son has red puffy eyes, this doesn't look like allergies to me, he looks horrible and its an on and off thing for about the past month... he also has been excessively thirsty and will drink an entire sippy cup within moments and screams until you get him more (he drinks at least a gallon and a half of juice/water per day)... he seems really tired and really irritable. His older brother was born with a severe coarchtation, a large VSD and ASD as well as a bicuspid aeotic valve and had surgeries to correct all except the valve. my youngest has been checked by a cardiologist (at 1 month old) and seemed to be fine, but has not been checked again - not saying it is heart related, but I did want to put that family history out there.
