Sleeping and Not-So Sleeping

Both boys are pretty good sleepers. Maceo's peccadillo is that he will call us up to his room after going to bed with issues like he is sweaty or his nose is snuffy. We've taken care of that by giving him a blue ribbon good for one nighttime visit. Most of the time, that suffices for him. Cassius has been a great sleeper. He goes right in to his bed, hardly ever with even a peep, seems to fall asleep within minutes, and sleeps all the night. Until the end of December. Then, he began awakening at around 5:15, calling and yelling and crying. We'd try to wait him out, but sometimes, to keep Maceo asleep, one of us would get up with him. This sleep change seems to have coincided with a lot more talking from him and recently, he's been sleeping until he's allowed to wake up (Thank God). However, last night, he awoke at about 11:30, which is very unusual for him, crying with what sounded like fear, which is also unusual. I went to him and tried to snuggle him back to sleep, but he was super tense, and he was super awake. He asked to go to our room, to go downstairs, to read a book. I kept trying to snuggle him back asleep, but after seeing that wasn't going to work, I explained that I was going to sing him a song, and then I would put him back in his crib. He wasn't happy about it, and he started to cry as I put him down. He sat up, and I asked him to lie down so I could put his "woobie" (blanket) over him. He wouldn't, so I left. By the time I got to bed, he was crying angrily, and then he started shouting, "Put my woobie on me!" over and over again. I went in, put his woobie on him, and he was instantly silent and stayed that way the rest of the night.
