Hey Mrs v! Sorry you arnt getting much in terms of sleep. Cc really was the final option for me, and tbh his age did come into account when making my decision, lo is nearly 11 months now, so I knew in my mind that he could do it but I had taught him that if he woke he would get a cuddle, I have now taught him a different method which luckily for us has worked.
Iv never been an advocate for cc, but as iv repeatedly said it was having so much impact and as I'm back at work we needed to at least try.
Leesey has put a link on one of her posts to a lady who has done lots of research, might be worth a look.
I think with any parenting technique people will always form their own opinion and hold different values, you must only do what feels right for you, and at a time when you feel you and your baby can cope.
I really do sympathise with mummys who don't get sleep, I do believe to an extent it is what we teach them, obviously if they are poorly this is not the case.
Would be great to see leeseys research, I think it will help a lot of mummys on here xx
