More than 1oz formula milk for baby. 3 days old

Hello mga mommies. Ask ko lang kung okay lang ba pa minsan more than 1oz pinadedede ko kay baby since parang bitin sakanya yun every feeding, minsan 2oz nauubos nya. Interval naman is 2-3hrs. He’s 3 days old palang. Napapa burp ko naman sya after. Enfamil A+ po gamit namin. Thanks. Sana mapansin
