My baby is eating way too much

Jessica
My baby is 1 month, he eats 4oz every 3-4 hours. When it comes to the night time he eats 4 oz and is constantly crying, we try giving him his pacifier he rejects it.. We try everything we can possibly think of but he's just not satisfied until he gets another 4 oz which totals up to 8 oz. Any suggestions or ideas that can help me ?
