My baby is formula fed and during the day she can eat almost 3.5 ounces, but at night it’s more like 2.5 because she falls asleep while feeding. Is this okay?

When I look it up, it says 4 week olds eat 4 ounces! She feeds every 2-3 hours. She’s wetting tons of diapers per day and poops 1-3 times per day. She’s on the smaller size, she’s about 8 pounds (maybe a little more) right now!
