bean - you're still standing! You can do this! MASSIVE support to you whatever you decide to do - although as others have said it sounds as if you've decided to go for CC because nothing else works.
I'll tell you (an abridged version of) our sleep saga. Things are going better in the Aldehouse now - wee boy (now 21 weeks) is sleeping from 8ish til 7ish waking every 4 hours for a feed. Which is so much better than waking every 1-2 hours before.
So. DS was always rocked/fed/carried in sling to sleep for the first 3 months. He slept in his cot next to our bed pretty early as co-sleeping just didn't work for us (he is a super loud snorty sleeper; neither of us did bf lying down well, so me and DS and Dh all ended up awake and pissed off anyway; I got cramp from curling up around him & couldn't sleep for fear of him being squashed... sound familiar?).
Then - shock horror! - one after the other our failsafe methods of getting him to sleep stopped working. As soon as we put him down from our arms he pinged awake and YELLED yelled yelled. We ended up doing this ridiculous slow knee-bounce, like demented Reggae dancers, for hours every evening. I started dreading night time. At about 13 weeks something in me just snapped and I though my God I can't carry on like this... so we just put him down (after bath cuddle song feed, the works) in his cot, put wax earplugs in, and took turns standing over his cot shushing/singing/stroking/smiling at him while he screamed. We did it for all his naps too. And when he woke in the middle of the night just 1 hour after his last feed.It was the hardest thing. DH broke out into beads of sweat and his legs shook; I felt sick. The first night DS screamed for 1 hr 14 (yep, 14) minutes. Next night 1 hour. It took about 10 days for DS to settle to sleep without massive rages but eventually he did...
...that worked for a few weeks until a) we went on holiday and b) he started teething. Then it all reverted back to the hell of Before, when I posted on this thread.
So basically we did it all over again, only this time when we stayed there with him he just got more and more enraged than we weren't picking him up. So we left the room and went back every 3-5 minutes until eventually he realised we weren't going to pick him up, he took the dummy and went to sleep. It took less this time.
Proviso: although DS now wakes every 4 hours and settles back to sleep immediately after a good bf, he still really hates going to sleep. I think he just hates missing the action and doesn't want to go to sleep. It's not the cot or the room or feeling abandoned because when he wakes up he gurgles happily to himself for 15 mins before we go to get him. He still cries when we put him down for nap and sleeptime, but he cries for less and less. It's not ideal, he's definitely not an angel baby, but it's way better than before... And! 3 nights ago he went to sleep on his own, no dummy, no tears! So it is possible. It just takes time.
Like you, we did this because everything else stopped working. The PUPD of the baby whisperer didn't work - DS just got more & more worked up and just expected us to pick him up.
It's HORRIBLE when nothing works and your baby is just screaming in your arms, on your boob, all the time. But what it seems to me is than my DS just ("just"! Hah!) needed to learn that he could sleep on his own in his wee cot in his wee room; that it was ok and lovely and safe to do so. He's still learning, but he gets happier all the time as he sleeps more.
Oh, and we put DS on his side with a rolled up towel, he sleeps loads better that way. Also we put him into his own room and that helped loads: I didn't jerk awake at every snuffle or sigh (there are lots of them) and I'm convinced that not hearing us there helped him not wake up so much.
Re naps: I'd say naps and night sleep are related in that if your DD manages to settle on her own she'll do it whenever. And if my DS reaches evening too tired due to crap naps it's much more difficult to settle him. But I wouldn't wait to sort naps before night sleep or vice versa.
What I'd suggest (take all this with shovels of salt!): put DD in her cot in her own room and be prepared for a week or more of AWFULness. Give her extra extra extra cuddles and love during the day. Up to you whether to stay in room with her or go in every so often. It will be so hard, but here are some thoughts which help(ed) us:
You've done everything possible to avoid this andnothing worked!
Nothing could be harder than the nights you've already endured.
You now have a plan, which will eventually have a result: no more dreading endlessly repeated months of might misery with no end in sight.
You're doing this also for your DD's sake so she can sleep better.
She will NOT be traumatised, hold it against you or hate you forever. DS now greets us with a massive gummy grin every waking time because he's well rested and happy. We play with him and carry him all day, he is so loved and he knows it well.
Advice given to us by friends (fellow survivors of sleepless hell) which helped:
Be consistent (don't cave in on day 2 and pick her up or whatever)
Count every tiny bit of progress as a massive achievement. It all happens in baby steps, every minute less of crying / more of sleep is a step in the right direction.
There will be setbacks and "relapses" because of illness/teeth/travel, but remember that once your baby has learned to sleep well one night she can do it again!
And to echo last post - have you checked it's not reflux?
Hmm. This is a mammoth post, sorry if boring or irrelevant.
LAst thing, then I'll shut up: my wee nephew screamed pretty much constantly for the first 6-7 months of his life. It seriously rocked my bil's marriage. They took him to a cranial osteopath person and apparently that really did help, so good luck to you on that one.
Over and out!
