What does your 2 month old act like / do etc?

my son is 9 weeks as of yesterday, and he rolls over jsut about every day, 2 times the other day right after the other, from belly to back naturally. He stares at ya, he flicks at his toys in his bouncer, and loves looking at the mirror ontop of his swing. When holding him under arms, he can stand up from a squat position, he also holds his head up like a champ, and for minutes at a time.
