My baby is literally an angel baby... she goes days without crying (to give an example) and is the pure definition of an easy baby. Super chill. Lately in the last week on 3 different occasions she cries hysterically from being sleepy.

Is this a developmental thing / purple crying ?

Anyone else going through this? Idk if I’m doing something wrong now. I’ve been more on top of her sleepy cues and even moved her bed time from 9 to 8 to settle her down earlier
