DS is 21 months and has been a good sleeper since CIO. Yesterday and today he has been waking up after he falls asleep (ex, last night woke up at 11pm, todays naps woke up 1/2 hour after falling asleep)---crying, very upset. Last night he was literally crawling up me to get to me and would not be put down without crying. We ended up bringing him into our bed. Today at nap he cried back to sleep in about 10 minutes.
Usually if he is overtired he has trouble going to sleep, this doesn't seem to be the case. And usually if he is sick he just wants some cuddling or you to rub his back but prefers to sleep in his crib.
I am not sure what is going on? Nightmares? Molars? He is eating great and seems fine during the day!
