Wow she is a quick feeder indeed! You are lucky.... my DD would take up to 1hr per feed in those early weeks so as you can imagine I wasn't doing much else but sitting on the couch! (but we did have weak suck issues and low supply issues because of that etc etc and other issues).

I remember my DD became a faster feeding around that 8-9weeks old mark (although she would still take 15mins or so at least) and from memory most other babies in my baby group were doing the same so that's all quite normal it sounds to me. Plenty of wet and dirty nappies, happy healthy bub......your DD is just becoming alot more efficient with her suck as she matures and develops.. all normal.

Sounds all good to me.... keep up the great work

(I love it when you can hear them drinking and sucking the milk out, it does get quite loud sometimes doesnt it? hehe)
