My 16.5 month old was a great sleeper. I could put him down drowsy and he would fall asleep. For six months he did this!
Now he is harder to put down in general and after an hour exactly he wakes up frantic and kind of sleep-crying. He absolutely will not CIO, never has. He's an escalator.
Could this be separation anxiety? He doesn't seem scared or dazed, just sleepy and won't stop crying. Clingy and we have to soothe him a LOT for like 20 mins to get him to sleep. (He's not sick, cold, teething, no new caregivers, no new patterns at all.) Is this just a phase??? Help!
