I am hoping someone might be able to help, as I am at my wits' end! My 22 month old was a very good sleeper until about the past 6 months or so. Progressively and off & on, things have gotten worse. She goes down at night around 8pm without a problem. When she is in a "good phase" she will sleep until 6:30 am or so. Nap time is usually 1:30-4 ish. This will be the norm for a few weeks. Then, unexpectedly, her whole routine will change. This week she slept through 2 nights only. Twice she was up at 3:30 and would NOT go back to sleep. I got her to lay back down, but 30 min later she was still wide awake, yelling for me. The other 3 nights she went down at 8pm and was up again at 10:30pm. She screamed, would settle down, scream again.... on and on for 5 hours! Each time I would go in to reassure her until she calmed and seemed to be drowsy, but about 10-20 min after I left the room she would call for me again. A few times I lay on the floor in her room until I thought she was asleep, but a few minutes after I left she was screaming again. Finally I think she tired herself from yelling so much and she fell asleep around 3:30 each time (and slept until about 8 am) I am exhausted because I am pregnant again, and I know I can't handle this with a newborn as well. Any suggestions??
