Baby was down for a nap earlier, I had a quick nap while DH went out for 45 minutes. I somehow slept through the crying on the baby monitor, when DH came back baby was crying and I was still asleep. No idea how long she was crying for, her eyes were red and she was upset. Shocked I didn't wake up as I always do during the night but must have been exhausted. So worried I've damaged baby by letting her cry for potentially a long time ( read about elevated cortisol levels etc) help me not feel so guilty
