I have a 15 week old and for the past few weeks he's become a very fussy feeder. He's EBF and until about 12 weeks was taking a daily bottle of expressed milk but then started to reject it. Shortly afterwards he also started to take much shorter breastfeeds and would scream if I tried to feed him more. As he seemed to be distracted I started feeding him in a dark room. He still screams for a while at the boob (sometimes quite a while) but then settles and has a long feed although I can't tell how awake he is when he does it. My worry is that he's not distracted, he's actually full and I'm overfeeding him by making him continue eating. And that in the short term I'm making him confused about dark room = nap or sleep and in the longer term that I'm going to give him some kind of eating disorder as he's not allowed to stop when he's full.
Does anyone have any wise words to help me?
