At her two week appointment she had gained almost a pound, so Dr said she is eating enough. (She's 3 weeks now). But this whole last week she's been waking up at night to eat and falls asleep within 5 minutes! And won't be bothered to wake up enough to eat more. She goes 4 hours regularly between feedings and will still go that long at night even after a shorter feeding. Her "normal" eat time is about 12 minutes total between both sides, I think I have a fast flow (when I pump I can get 2-4oz in 5 minutes or less). And she tends to eat quickly for the first couple minutes and then just kindve doddle for the rest of the time until she falls asleep.
