Most filling Enfamil formula?

Jessica
Which Enfamil formula have you mommies used that seemed to be more filling to those little ones that like to eat a little more lol my 5 week old is having 4 to 5 ounces every 2 hours during the day and 4 to 5 ounces every 4 to 5 hours at night. He tried him on Gerber good start he hated it and he is now on Enfamil newborn and does great but just doesn't seem to get full. We are trying to decide which formula to go with so we know what to tell wic since they are hard to deal with in our area about switching formulas 😣
