When my son was 18 months, we had had one too many 10pm bedtimes so we bit the bullet and did CIO. I was amazed that is gotten to that point, but I had, and it bloody worked!! Within 4 nights he was going down easily and awake. We have honestly not had one single problem since then, he's been great until 2 weeks ago when he began screaming the house down. So now, at age 2.5, I find myself sitting next to his cot every night hissing "close your eyes" periodically and tiptoeing out when he's asleep.
We tried a refresher on CIO. Disaster. He was inconsolable and it took an hour to calm him after I left him for 3 minutes.
He's still in a cot, in a sleeping bag, and he will nap in the car, and very, very rarely on the sofa if he's had a particularly busy day.
What can I do??! Help me solve this sleep problem, please!!
