Cool, thanks for the update Kaz, I was wondering if there was an update at the end after reading the whole thread!

Reading with interest, DS is 22mths, co slept since birth, currently night weaning, waking 4-5 times a night, staying awake 1.5-2 hours at one wake up point. Hoping the fog clears soon, as I am really relating to the depression you speak of :/
