Newborn breastfed baby poop normal or no

Newborn breastfed baby poop normal or no ? First time mom I’ve noticed today he has been a lot more fussy after eating today when usually he goes straight to sleep till next feeding! He’s 7 days old and we are giving him 1ounce every 31/2-4hours he’s weighing in at 7lbs I dont know if he’s not getting what he needs from my breast milk or should I be feeding him more every feeding time now? And if I should how much? I don’t wanna over do it
