I have done CC successfully, with four other children, and the longest it took was 5 days, and at that dd was sleeping through the night, it just took her that long to settle to sleep when put in her cot. Ds4 is 12 months. This is day 6, on day 4 it took over half an hour for him to settle at bedtime, and he cryed for and hour and a half in the night, then slept until 8 when I got him up. He got his daytime naps in the car, as we had to be somewhere. Day 5, he again had his naps in the car, and took half an hour to settle at bedtime, woke at 4am for over half and hour, dh was into him twice, then woke at 6 for 20mins, dh into him once, and when he woke at 8 I got him up. I am dreading nap times today. What is the longest CC took to work for you?
