6 week old EBF

My 6 week old baby is ebf and honestly he does great at night sleeping. Our ped said at his follow up right after birth he had already passed his birth weight so I didnt have to wake him up anymore after 4 hrs, just let him sleep. He eats great in the day also naps of course hes a newborn, dirty diapers around the clock sand gaining weight properly… At night he’s been giving me 5 hr stretches, is that ok? Like will my supply be okay? I just want to know if I need to pump at 3 am or something?
