Hi there
I see you are asking for how CC works rather than opinions on if it's a good idea or not - totally understand as was at the same stage 2.5 mths ago.
We did this at 6.5 mths and it worked well. Our baby was good at going to sleep (we had had a good routine from v early on) but was waking up more and more frequently during the night and unable to self settle.
I did my research and then did it the following way:
- put to bed as normal
- when he woke up the first time, immediately went into him to reassure him (as usual)
- did NOT pick him up or feed him, or turn the light on (this was not usual - previously I would have tried to soothe him & would have ended up feeding him)
- patted his back, stroked his face, told him we loved him, all of that - but NO picking up
- left the room again after one or two minutes - i.e. not trying to wait till he was asleep again
- waited 2 mins, went in again, same routine
-waited 3 mins, ditto
- waited 5 mins, ditto
- waited 10 mins (but actually he stopped crying after 7 and then slept through till 7am the next morning!)
The whole thing took 25 mins in total, including the time I was in there reassuring him. V important to look at the clock as listening to your baby cry for one minute feels like 10. The next night was about the same, but the 3rd night it took more like 10 mins, and since then he has been a fantastic sleeper - although, that said, last night he woke crying about 40 mins after he'd gone to bed, which was very unusual. I am pretty sure it must have been a nightmare, so obviously I went in, picked him up, reassured him, etc.
I guess for you, the issue is the going to bed rather than the waking up, so you could do the above as soon as you put your baby to bed - i.e. rather than waiting for her to wake up the first time.
I also had friends who said that for them, going in to reassure their babies actually made it worse - made it more difficult for the baby to calm down and go to sleep. I am sure that the best method of doing anything varies from baby to baby - and, of course, CC will not work for all babies at all, although it did for us.
I think the main point is not to pick them up, feed them, or give them anything which they could not do by themselves (i.e. if your baby can find a dummy and put it in her mouth by herself, then it's fine to give her one, otherwise, don't do that either), so that they learn how to sleep by themselves with no props.
Obviously v controversial etc but I decided I would rather have a baby who slept well than one who was exhausted from waking up - especially as I had heard of quite a few 2 or 3 year olds who were still waking up several times in the night.
Hope this helps a bit.
