3andamdone, I'm sorry, I have only just seen that you asked how we were. Thank you for that, it was very kind!
I've just come back to this thread as I thought I'd update it in case it becomes useful to anyone else in the future. I certainly know I searched old threads for others experiences. This is a long post, but hopefully worth typing out in case it helps someone else later on.
I decided against doing CC at the time I last posted, as like FATE suggested, I didn't feel like I could be sure he didn't need the milk overnight.
Instead I decided to really work on our daytime routine and see if I could crack the daytime naps. A couple of weeks of hard work, but we got somewhere and DS started getting pretty reliable at going down for 1.5-2hrs at about 10am. I was then aiming for another nap in the afternoon, about 2/3pm, but that was a bit more hit and miss.
Fast forward to last week.....DS is now 7months and has a pretty reliable daytime routine. He has also taken to weaning really well, and is having 3 decent 'meals' a day, with milk feeds in between.
Overnight sleep was still pants though, so last week I reconsidered CC.
DS was (most of the time) self-settling for his morning nap so I knew he was capable of going to sleep on his own, and now he is eating lots during the day I felt more confident that he wasn't actually hungry at night....so I made the decision to try CC.
I've changed our bedtime routine a little. So rather than bath/lights off/feed almost to sleep/put in cot, I now do bath/feed with lights on/story/lights off/in cot awake.
First Night
I put DS down awake, he cried. I didn't pick him up, just put him back on his tummy (how he sleeps), gave him his comforter, and rubbed his back while talking to him calmly for a minute or so.
Then I left. Waited 1 min before going in and doing the same. Then 3 mins, 5 mins, 7mins and 10 mins. I'd already decided that 10 mins was the longest interval I felt comfortable with so would have done repeated 10 minute stretches after that, but in the end I didn't need to as DS was asleep by half way through the first 10mins.
After that, i said that if he woke up after 11pm I would feed him, but any earlier and I would do CC again to resettle.
He woke up at 10pm, so I did CC again, but this time it took less time and he was asleep again before the end of the 7min interval.
And then he slept til 4.30 am 😳 I actually woke up at 2am and went to check he was still breathing!
Gave him a feed at 4.30 and he slept til 7.
Second day/night
DS went into his cot awake and self-settled for his morning nap. I needed to do CC for his afternoon nap, but it only took 10mins or so in total before he was asleep.
He self-settled at bedtime, then woke at 12.30 so I fed him. I heard him wake at 3.30am but he settled himself within a minute or two and went through til 6.30am.
Third day/night
DS self-settled for both daytime naps, and self-settled at bedtime.
I heard him wake at 12.30, but he wasn't crying so I didn't go to feed him straight away and he went back to sleep within a few minutes. He then slept til 4am, when he had a feed and went back to sleep until 7.
No CC needed all day 😊
Fourth Night
I never expected DS to suddenly start sleeping 7-7 and go 12hours without a feed, but by this point was clear that he could go from bedtime til about 3/4am without milk.
He obviously needs 1 feed over the 7-7 period, and when he had it needed to be consistent or it would be confusing for him. So I decided that I'd rather do that before he wakes for it so that I can maximise my own sleep.
So since the fourth night, I've been lifting him out of his cot at 11pm and giving him a feed. He pretty much stays asleep while I give it, so once he's done I rub his back and talk to him just enough to rouse him to open his eyes. Then I can put him back into his cot awake, and he'll go back to sleep.
And since then, he has been sleep through from 11pm-6.30/7am!!!
We've had one night when he woke up at 4.30 and needed me to go and settle him, and a couple of naps where we've had to use the CC, but now it only takes a few mins and he's asleep.
It's amazing the difference getting some sleep has made to all of us. I feel like a new woman 😂
So, as I said at the very start of this thread back in January, I know controlled crying is a controversial subject. But for us, DS included, it has been so worth it.
Only really 2 mildly horrible nights, and since then we are all so much happier.
(I'm sure someone will come on and tell me I've permanently damaged my son, but whatever. This is MN, it's always going to happen!)
