Advice on Feeding! HELP!!

Bear

So my daughter weight at birth was 9lb and she is 2 weeks old now and is eating 4-5 Oz every 3-5 hours. I feel like that's a lot for her only being 2 weeks old. The pediatrician said they should be eating 2-3 oz every coupke hours. Should I just let her eat what she wants? She doesn't spit up or have any acid reflux, she burps amazingly good. She on Similac Pro-Advance.
