It sounds to me that this boy has a bigger appetite at night and could possibly have a small snack to possibly tid him over to the morning. He was 11 pounds at birth and is now 22 pounds a very good appetite -- this may be the one that "eats you out of house and home". Try adjusting his solid food intact a bit before bedtime to see if this works. If so, you may be able to cut out a bottle or two in a short time. Since you let him have his own scheulde, you may want to gently change it for him and put him on a schedule for food. Good luck.
