Question. My 1 month old is CONSTANTLY hungry. When I say hungry he will drink 8 oz of formula at once if I let him. I have been keeping it at 4 oz because everything I have read says feed 2-3 oz until 3 months. As soon as he finishes a 4 oz bottle he cries and cries he gets burped while still crying and after burping still cries until I stick another bottle in his mouth. You can't trick him an give him a paci because once he sucks an knows nothing is coming out he spits it out and cries. He will fall asleep eating an when you take the bottle out while he is sleeping he doesn't cry, then he gets burped while asleep an then he wakes up 30-45 mins later hungry. This is literally around the clock. Another thing is here lately since this whole extreme eating thing had been going on he wakes up if I lay him down then cries until he turns purple, if I hold him he doesn't wake up. Then the feeding cycle of course starts over again. I have switched his formula from gentle lease to gentle lease no GMO because the other one made him stopped up . He went for his 4 week check up and weighed 10 pounds and when he was born he weighed 8.7. They said he was on the right track, asked if he is throwing up/ spitting up which he is not and they told me that him eating as much as he is, is fine unless he starts throwing up. I personally feel like when we go through a large tube of formula a week he is over eating. He is pooping once a day so I know he isn't constipated, he toots ALL DAY LONG literally like an adult would and that is apparently normal I just didn't expect them to be so often an so loud that it sounds like he is pooping. He is already in 3 month old clothes and 23 inches long.
