I think my supply might be high, as I feel quite full more often than I did but that is prob because she is feeding less often - I used to feed her every 2 hours during the day but now she sometimes goes 4 hours during the day. I read on Kelly mom that some babies seek comfort after they have finished their feed and don't want more milk - they get fussy when the milk comes through. Think this might explain it. I was always looking forward to the time when feeding sped up a bit but funny how it has completely thrown me as to what is going on.
Yes, I remember when my first baby went from 40-60 minute feedings to 5-10 minute feedings. I had SO been looking forward to feedings getting faster, but when it happened I didn't know what to do with myself or with her! I had gotten used to long sessions of nursing and reading novels, and all of a sudden I couldn't read more than a couple of pages before needing to entertain her in some other way!
Fast letdowns can definitely cause fussy feedings and a dislike of "comfort" nursing. Have you tried feeding baby in a reclined position? And how has her weight gain been so far?
