Lo only eats for dad? Help!

My lo is 3 months old. When I feed her, she only takes about 3 ounces at a time. When her dad feeds her, she will take 5-6 ounces. I barely get 22 ounces out of her most days, while he gets 30! We feed her the exact same way, in the exact same place. We don’t talk to her while she eats, because she would rather talk than eat and will stop eating. So I know it’s not that either. We both have great relationships with her, but she definitely wants me when she’s upset. So why doesn’t she eat as well for me?
