Differences in bottle-feeding

We were remarking about the difference in feeding styles of the 3 children.  Domu was the most frustrating to feed, taking up to an hour to finish 30 ml of milk.  He would fall asleep between each ml.

Pia was easier, even knowing (even during her first days!) how to pause and regain her breath while trying to finish 30 ml. 

But Samuel is the fastest, now finishing up to 150ml in just 15 minutes.
