Can a newborn (2wks old) really have gotten enough from a feed if theyve only nursed 10 mins?

Baby sometimes will nurse like crazy AND take a 2oz bottle on top of that, other times she’ll nurse for about 10 mins & pass out & I can’t seem to get her to want to take more than that. Then like one hour later, she wants to feed again.

Does this sound like normal newborn behavior?

And is it possible that she’s actually gotten enough in the mini feed?

Thx
