Yes jubbilicious we decided to go in at intervals of 5, 10, 15, then 20 minutes. But we never actually got past 15mins without him falling asleep. Sometimes he fell asleep after just 5 or 10. At each interval one of us goes in and strokes his head or his back and say 'shhh..' a few times just to reassure him that we are there and everything is ok.
At the time it feels horrible [the crying] especially if you are on your own, but it's over pretty quick and then i personally just felt amazed that my DS actually fell asleep on his own, and slightly relieved - mainly because i worried that he was going to cry all night but that was not the case at all.
When you see an improvement you know its oall worth it, and we saw one straight away really.
At nap times we stick to the same rules with the intervals and everything, you have to really, consistency is the key thing to get this to work. Our Ds has a nap everyday around mid morning which usually lasts a couple of hours. He hasn't cried longer than 10mins when going down for his nap, somethimes hasn't cried at all.
As for the night feeds - our DS has always been a hungry baby and up until recently was having nightfeeds, i believed the main reason he was waking was due to hunger. But after working with my HV and doing a food and drink diary for him for 2wks, my HV showed me that he consumed more than enough calories during the day and he didn't actually need the nightfeeds at all, he was just having them out of habit. Once I realised this i began gradually reducing his nightfeeds until they were gone and it wasn't hard at all he actually dealt with it really well. So i would say, as long as you're sure your baby is eating enough during the day, maybe check with your HV first, but why not try cutting out the night feeds before you start CC. That's what i did, as soon as i realised he can actually get throught the night without a feed then there was no reason he couldn't sleep through the night. So once he got used to there being no more night feeds, thats when i decided to go for it.
Now that i'm doing it and seeing results [ he went down tonight without so much as a whimper, and im confident he will sleep through again, fingers crossed] - i only wish i did it earlier. I think 7 and a half months is a good age to do it, my HV said its the perfect time developmentally, but it took me abit longer to have the strength to do it. My son was ready - but i wasn't.
So, I say go for it. As long as you feel confident that if you start it you will see it through, if you're unsure about it then build up to it gradually like I did, reduce the nightfeeds, up the daytime calories by giving him a supper, i tried giving him some baby rice right before bed on my HV's advice and that seemed to work well. Make sure your bedtime routine is solid and consistant and try not to pick him up or feed him everytime he cries at night or get him in your bed [- all mistakes i made for a long time]. Get support from your partner or family or friends, i honestly find it so much easier to cope when my partner is here with me.
Good luck x
