Is this normal?

Elizabeth

So I just started breastfeeding my 1 week and 3 day old and he falls asleep after 5 minutes of being on one boob. He’ll wake up an hour later hungry again and does the same thing. Is this normal? I started with formula at first since he wouldn’t latch for a while and now have to use a shield. He usually takes almost 3 oz on formula so I’m confused. When I pump I only get 1.1 oz out of both breasts combined so I’m not sure if he’s getting enough. I’m new to all of this.
