Anybody else’s baby just “graze” all day?

Kelly • Mama to 1 toddler girl (and baby boy due in August!)

Does anyone else’s baby just kind of “graze” on milk all day? When people say your babies drink 3-4 oz every 3-4 hours, are you saying that your baby downs a 3-4 oz bottle in ONE feeding session, waits 3-4 hours, then repeats? I’m anxious over here bc my 13 week old is generally eating about an ounce an hour of expressed milk when I’m away for the day at work (so 10-12 oz while I’m gone for the day from 7am-5pm) but it’s in tiny amounts spread across the day. The nanny says she takes 0.5 oz - 1.5 oz at a time - so sort of grazing throughout the day. Is this normal??
