I've been trying CC with my 6 month DD who was waking every couple of hours. It's working reasonably well as the night wakenings have reduced to just two. Here's the scenario:
Bed time 10 mins crying
1st wake up any time between 11:30-2pm which she will eventually self settle after one check.
2nd wake up: this is the problem. The other night she woke at 3:20 and still hadn't settled back to sleep by five so I gave in and took her into bed because I just thought she was never going to settle. Should I have left her? And persevered ? Also I thought CC was supposed to stop the wake ups ( she's not waking for hunger) id really love to hear your opinions and experiences.
