Almost 1 month and eating to much?!!!?

KT
He eats 3-4 ounces every 2 hours during the day and 3-4 ounces every 3 hours at night. I thought maybe it was a growth spurt but if it is we're on day 5 of it. Is there anything I can do to help him sleep longer at night? He's only been napping 1 maybe 2 times a day for maybe 2 hours. He's formula fed
