DD is four months and absolutely will not nap without screaming herself to sleep. And I mean really horrible, painful sounding screaming. I hold her, rock her, feed her, and I've tried reducing time between naps and it makes no difference - she just screams for half an hour before finally just exhausting herself. When held she pulls away from me, hits me and seems to not like it at all, but equally will not fall asleep by herself in her cot if I put her down when she's sleepy and calm. Can anyone reassure me that I'm even providing any comfort to her?? I have no intention of doing any kind of CIO on her, but it feels like she just hates me and being rocked/soothed/walked around/cuddled etc is just upsetting her
