My 6 week old is a very fussy nurser in the evenings. She wants to nurse almost constantly from 5:00 until bedtime but she never nurses for very long during these sessions. She also goes on and off the breast a lot and cries and fusses. A few days ago she was having such trouble nursing that after she fed for about 3 minutes and refused to latch on again I pumped about 1.5 oz of milk and just gave it to her in a bottle. She was like a different baby after that. She stopped fussing, fell asleep easily, and slept for her longest stretch ever (5 hrs.). I did this a few more nights all with the same result. A few days ago I stopped giving her the bottle of pumped milk and just let her nurse as she wanted. Her last few sessions were very short again but she did eventually fall asleep. However, she is back to only sleeping for 2 - 2.5 hrs before her next feed. So, my question is, how bad is it for me to give her an extra 1.5 oz of pumped milk in a bottle after she nurses for the last time in the evening? If I do this am I overfeeding her? She really seems to enjoy the extra milk as she calms down and sleeps well right after.
