Yet I just expressed a load of milk, plopped it in a bottle and she downed it in one. She has only ever had breastmilk, mostly straight from the udder (has maybe had less than 10 bottles of EBM in her 16 week life). It's doing my head in. Anybody would think I was poisoning her. Breastfeeding going fine until about ten days ago, she has no discernible cold or nose blockage, and feeds fine lying down. She's my 4th baby and with 5 years of successful breastfeeding under the belt, I'm trying not to take it too personally, but what the deuce can the matter be?
