My son is a month old today and is 12 pounds. During the day hes eating about 4-5 ounces every 3 hours but before he goes to bed the last few nights he's eaten like 6-8 ounces then slept for 5 hours. Last night he ate 12 ounces within 3 hours. He's not vomitting. I tried to stop after 4 ounces but he screams and cries and roots like crazy until you give him more. Anyone else have a huge baby that loves to eat?
