Is my baby eating too much?

Juliana

My daughter is exactly a week old today and all of a sudden she has started eating every hour instead of every 3 or 4. She drinks my breastmilk but from a bottle I don’t understand why she’s eating so much. Is she not getting. Full she’s only a week old she should only be eating 2-3 ounces and she’s eating that every 2 hours. Please someone tell me what I should do or if this is normal.
