Sorry, probably talking out of my a*5e but I remember reading up loads of techniques when I had huge problems getting ds to settle.
You can do something like comfort til they stop crying, then ignore in the room for a set time. I think it's meant to be less harsh than CC, but I think I would find it harder to do if I was in the same room.
i did feebly attempt this kind of cc but found it enormously distressing as lo was crying and imploring me to pick him up and offer comfort. I did cc with really small intervals (2,2,4,4,5,5,6) but left the room each time. Easier on both of us imho. How old is your lo?
I really don't want to do CC but we're nearing the end of the tether. We're knackered. We were getting somewhere with softly-softly sleep-training, but then he caught a cold and cut his first two teet and it all went pear-shaped. Last night I just gave up trying to resettle him and took him into bed with me and let him feed whenever he wanted.
I've done CC before, with dd, and I know that it can be a really quick fix for the problem. But ds doesn't have separation anxiety, and I don't want to trigger it. Also, dd didn't suck her thumb until we did CC, and then she became such a strong and constant sucker that it has damaged her jaw.
We did cc and left the room - like cruisemum. My DD got more workrd up by GW and PU/PD but I do know others it works well for. I suggest you get some books from the library so you understand each technique. Get DH to have input and choose the method you both agree on. Set a day to start and go for it. Naps and all. Thant way DS won't get mixed messages.
DD always deteriorates after teething etc but I reintroduce the routine and she often responds just to that, I have had to re-do CC a couple of time tho.
