7 week old still eats every 2 hours❓ is it okay❓

My 7 week old baby still eats every 2 hours (about 4oz). I read that she should be going longer stretches by now between feedings. She has been eating 4oz for the past couple weeks and most of the time finishes her bottles, but sometimes she cluster feeds and is always hungry for the next bottle 2 hours after she began the last one.

Is this okay/normal?
