My 7 week old daughter just doesn't seem to enjoy her milk. She generally only feeds for 5-10 minutes every 2 hours and retches and gags a lot during the feed. If I keep her at the breast or offer her the other side she gets hysterical. She's gaining weight but has dropped down the percentiles from 75% at birth to 40% now. My eldest was such a good feeder, and loved his milk (fed him til he was 2.5!!) so I'm a bit stumped and worried. She's been cutting back daily on her feeds this week, she does have a slight cold but nothing serious. Lots of wet nappies and she poos once a day (all normal - no green or frothy stuff) Any ideas? I'm starting to feel like there's something wrong with my milk :(
