tourette’s/tic-like movement in baby

my son is 6 going on 7 months old and i just noticed today him doing movements which i can really only describe as looking like tics.

i wish i’d gotten video, but as he was looking up at me, he started kind of twitching his head down and blinking hard, along with kind of twitching his arms/hands.

like i said, there’s no other way to describe it besides looking like someone with tourette’s. i just didn’t think tics could possibly show up this early. so what could it be?

is he just a baby being a baby? i’ve never noticed this before until today and he’s done it a few times.
