So my son Max ate 12 ounces in one feeding today and he is only 3 1/2 months old. Is this a normal phase? It seems crazy to me. I don't know if it is just a growth spurt or what. He sleeps through the night but maybe he is just so hungry in the morning he eats a lot. Should I wake him up at night and feed him instead? He gets about half formula half breast milk most days. He has only done this a couple of times and it just worried me a little.
