Just a little tid-bit. My cousin drooled. I am 39, he 34. He graduated from University of Austin, some years back. We affectionetly talked about his drooling about when he was 3,4,5. He would wet his tee-shirt, pants and anything aroung him. He is a Software engineer now. He's doin really well, married , house....you see where I'm going?
Dont sweat the small stuff.
Some kids just drool.
