Fussy boy

Almost 7 weeks and yesterday he decided to start being a punk lol. He doesn't want to sit or lay or be held, he doesn't know what he wants haha. He must be going through a growth spurt or something. He just likes to scream, not a pain or hungry scream, like a new type of pissed crying. Today he napped for 3 hours straight and now wants no more than 2 oz of milk...but every hour lol. Anyone else going through this?!
