Decrease in feeding

Amelia

Anybody else experience a decrease in ounces taken in during the day? My 2 month old has been at 6 oz of formula for the past month and now since like last week he’s only been taking like 3-4 ounces during the day sometimes he will take 6. He will also go hours without at night and only take like 4-5 oz sometimes.

Is this normal?
