My son in 5yrs old. He can sit and watch a movie or have a book read to him, but he picks at his nails and goes like stur crazy when he's kept in a small place (like my parents 5th wheel camper). My mother swears that he is ADHD because I have a cousin that was diganosed (but I totally don't think he is, but that's another story) and my son's dad was put on meds to it, but come to find out that was only because his parents were lazy. My son can focus to learn his weekly verse for church. He can sit still at the doctor's if need be. But I mean he's 5 yrs old. And a boy. Aren't 5yr old boys like that?
