My 4-month old EBF baby has always been a champion feeder - we both enjoyed breastfeeding and there were never any issues.
For the last couple of weeks however he started being really fussy at the breast, sometimes he takes a couple of sucks and then turns his head away and starts crying and arching his back. If I attempt to latch him back on or even try different bf positions he goes hysterical. He does seem hungry though as when I gave him a bottle of expressed milk he drank it all. I also tried feeding him at different times and environments (after nap, before nap, in the wake window), dark room without distractions etc.
What's odd is he feeds fine at night, he's calm and takes a full feed. During the day it's a real struggle though.
Any ideas how to sort this? I was thinking maybe it's an ear infection, but he hasn't got any symptoms.
