Thick question - sorry! When my ds possets, I'm never sure whether that's an indicator that he's full and finished feeding, or might want a bit more to replace the bit that's come up? What do others do? (Except for learning your baby's hungry cues and acting accordingly - I'm working on that bit!)
My DS would feed, posset a bit, then soon afterwards would be hungry. He seemed to do more possets if he'd fed really quickly (if my breasts were full after sleeping for a few hours, for example, and he was hungry and gulping), but would need to replace the milk he'd posseted after that.
