How can i fill my 1mo up?

Is there anything I can do to fill my Son up? He is a month old and constantly hungry! If he is awake he wants to eat! He will spit pacifiers out! He stays awake for like 3 hrs n the whole time acts like he is starving! He will take about a 20 min break but wants back to eatin again! I put him on formula Cuz low milk production but anything I can do?
