Baby eating so much

M

anyone else have a baby who eats A LOT. The last 3 days my son will eat 4oz if breast milk and then an hour later be screaming and eat another 2-3 oz. he’ll do this from the early night up until Like 5am where he’ll finally give me a 4 hr stretch. I don’t mind to keep feeding him I just never heard of this where every night he’ll like cluster feed. He’s 3 weeks old.
