I recently began pumping and giving my son a bottle in the middle of the night. (Husband gives bottle so I can sleep on weekends!)

I calculated how much breast milk he should get with a range. He should have drank 4.5oz and the high end was 5oz. After my husband fed him he was still hungry so he gave him more and he ended up drinking 6.4oz total.

That’s obviously more than he should have gotten. Is he just drinking more because the bottle is easier? (Low flow breast like nipples used)

Any and all suggestions and insights welcome!

He is 5 weeks old and a week and a half ago he was 11.3lbs.

Help?!

Thank you!!
