Hello and welcome to BW forums
Are you familiar with the EASY routine and BW ethos? Have you read any of the books? That would be a really good starting point if you have not yet familiarised yourself with the idea.
We do not agree with CIO or CC of any sort and these would not be methods we could support you with at all. Please see these links:
https://babywhispererforums.com/index.php?topic=19710.0As you have use a CIO method for sleep training at night I would recommend reading this link about regaining trust of your LO
https://babywhispererforums.com/index.php?topic=126141.0Depending on what you have done since CIO was used you might consider a phase of regaining trust - BW methods for sleep training are entirely based on trust, trust that a parent will return and respond *every time* he needs you with no delay. The methods are going to be hard to employ (or not work) if trust is broken. Perhaps have a read and give it some thought.
We can certainly support you with your routine and respectful sleep training methods here if you feel ready.
In addition to the above links I think this one could be useful for you, Pantleys no cry method for weaning nursing to sleep and throughout the night, also for weaning co-sleeping, there are different parts to the link, it would be helpful to get a general idea of all of it and then adapt the method to suit your own circumstances:
https://babywhispererforums.com/index.php?topic=52857.0Pantelys methods work very well alongside BW and I would suggest this as a slower and more gentle way forward at least in the early days and particularly as there may be some trust issues impacting your LOs sleep.
Whilst you have a read of those links and familiarise yourself with the EASY routine could you also observe over the next few days and write down exactly when your LO eats and sleep, how long the activity time is - this is the first stage of introducing EASY. You can then post the EAS times here and I will have a look for you and can then hopefully suggest a suitable routine and help with your goals of independent sleep and weaning BF.
There are also lots of other FAQs on the site you can have a read around - the more you know and understand about the methods the better your experience will be when you begin. This is unlikely to be a "quick fix" but rather a long term solution. I think of independent sleep as a gift you give your child, it can be hard work but it is ever so worth it.
I hope this helps.
