Baby not feeding as long

Ki

She will be 1 month tomorrow. We are EBF. Feeding sessions used to take 20-25 minutes. Lately taking 15-18 minutes. As in, after this time she’s no longer accepting food and latching after that.

I have a good supply and let down is quick and strong. She’s also much more alert and actively feeding the whole time than she was a few weeks ago. She was born at 7lbs 2 oz and is already up to 8lbs 10 oz by 3 weeks old.

Is she just getting more efficient with feeds? I don’t want to force feed her just make sure she has enough!
