We have been a co-sleeping family for a couple years now and I recently noticed that DS2 (8.5 months) sleeps better in his crib than with us. I think our movement and the smell of me (BF) wakes him up. Anyway, I recently started putting him down in his crib with the idea that when he wakes up in the middle of the night I will then bring him into the bed. Surprisingly, if I put him down in his crib he will more or less sleep through the night. HOWEVER, he does wake a few times. Sometimes he just stirs and makes some sleepy noises and go back to sleep. Other times, he will cry. Its always a short cry, less than 30 seconds, and then he's back asleep. Due to exhaustion, I have been waiting to see if the cry is the 30 second cry or more before going to get him. If more, I always go get him or make DH :)
Am I letting him CIO by not responding to the brief cry?
Please be honest.
