Jack just turned 8 months and has been sleeping through the night (7:30 to 6:30/7) since 4.5 months old. Lately he's going through LOTS of changes with his mobility and also getting teeth. He isn't crawling yet, but does lots of hands and knees/rocking and scooting and sitting and rolling... everything except crawling.
Over the last week or so, he's been waking at night. SCREAMING. Sometimes I go in and he's twisted in his crib, so I just fix him and leave. Other times it appears he's fine, so I just reassure him with a pat and some quiet words and he goes back to sleep. I try not to pick him up, although sometimes I do if the patting/whispering doesn't calm him.
It is almost like he's having a bad dream, or possibly in pain from teething. He has tears running down his face and everything. The other night this happened 4 times, but the next day he had two new teeth that had popped through on the top.
So my question is, it is okay to go to him, right? I have never done CIO, and never had to thanks to Tracy, but now I can't tell if maybe I'm being manipulated a little bit, and he's crying to see me come running. I don't stay longer than a minute, and I leave once he's calmed down. Sometimes he starts up again when I leave but calms and is back to sleep within less than a minute.
I know the issue the other night was teeth. And the last two nights he's slept through without a peep. Could he be having nightmares? Am I doing the right thing by going in to calm him/straighten him out or should I leave him alone?
