Two days ago our 9 - almost 10 - week old breastfeeding daughter started fussing during evening nursing. Yesterday it was better, there was little screaming (though there was some), but today we're back to really loud and intensive fussing. It's almost crying. And she seems really angry.
For a few minutes she feeds OK - then fusses - then, sometimes, feeds well for some more time. It does not seem to be connected to whether the milk is actually flowing from the breast.
There's nothing that we can think of that had changed in us, our home, the way we feed her or hold her. What could be the reason of her fussiness?
