5 week old eats so much

Lisa

Every night we start bedtime at 730. My 5 week old starts by nursing on both boobs. Then he also has 120ml of pumped breast milk. And once in. While he will have another 50ml of formula. Then he gets rooting for more. He then gets breast fed once more. At that point it's almost 10pm and all that food and usually 3 diaper changes. He's sometimes ready to sleep. This is litterally nightly. The food amount is increasing daily too. His last weigh in he's 1 lb higher then he needs to be. He's also very healthy. Anyone else feed this insane amount nightly?
