Is it normal

For my 2 week old to take an hr to eat a bottle? Also she eats 2oz every 3 hr with 1 oz in between and sometimes she’ll eat the full 3 oz every 3 hrs but most of the time it’s 2 oz and wants another oz an hr later.

But the real question I have is why does it take her 1 hr to drink her bottle? It’s making nights so hard. Being up so much feeding and having to get up super early and staying up all day is getting hard with two toddlers and a new born . I’d get more sleep if I could figure out why it takes her an hr to eat 2 oz
