Hi bean. Have been reading this thread since the beginning but have only just decided to post and tell you my story.
I have a now 1yr old ds who also doesn't sleep. Its a two-hour cycle like clockwork for him and I wish I knew what he wanted when he woke up! It can take anything from as little as a cuddle and back to sleep, to a drink of water, to a full blown tantrum, to sleeping in the bed with me or to just simply be awake (yes, I've done a 3.30am start to the day before).
He has always been a terrible sleeper and was still waking for milk in the night at 8 months when I decided to try a method of cc with him to get him off the feed as he was having more than enough to eat during the day and I was worried he was over feeding! I also had to go back to work full time and wanted to sleep. It took 3 nights - first night 45mins of crying, second night 2 hours (awful!) third night 15 mins then he slept through.
BUT... it lasted 3 nights. He then got a cold, coincided with teething (4 coming through at once) and he was up hourly screaming. Since then he started to be sporadic (occasional sleep through with the majority night wakings) but we never gave him milk and just gave cuddles, nurofen when needed etc.
Now I'm not sure what is wrong. I have no idea whether he has "learnt" bad habits from us not being consistent in our choice to continue cc. Or whether he just wakes and that is him. I am unsure whether you can "make" a baby sleep if he/she doesn't want to. I know cc has worked for many but tbh I really can't do it again. Its not like it had the lasting effect many make out. I was under the impression you only need do cc once and your baby learns but thats just not the case. As soon as something happens (illness, teething, developmental stages) they go back to waking and you have to do it all over again.
So my advice is to really think hard about it before doing it as it is really hard (emotional, physical) and it may not be the quick fix solution you think it is. You may have to do it again and again and again.
Also, as for naps: my ds has a two hour nap after lunch which is apparently the perfect amount and it still bears no relation to his night sleeping. And yes, we have tried keeping him awake, shortening naps etc but nothing works. Honestly, I have tried it all. And whilst I too am on the floor howling and howling at wanting more sleep and not knowing what to do, I am slowly resigning myself to the fact that some babies (mine) don't sleep and may not sleep for some years. Scary thought, but its reality I guess.
Oops, another point I wanted to add: I know my parents did cc with me. Apparently I too was a nightmare sleeper who would throw myself out of the cot. They ignored me as much as they could (put pillows down so I didn't hurt myself) but generally just left me to it. Now whilst I think I am now a well-adjusted adult with no real problems, I have had a recurring dream since childhood about shouting and shouting something important and no-one hearing me - it is only since reading about sleep probs and cc that I have started to wonder whether there is a relation here and the dreams are the lasting affect of cc on me??
Sorry bit deep there.
Good luck with everything. Whatever you decide remember it is your decision. Do make sure you have the backup of your dp before doing anything as you need all the support you can get.
I'm off to see my GP later (1st year injections) and will be asking about sleep help myself. But I know they won't be able to offer me a pill that will solve all night wakings forever... if only it could, eh?
