I do not know the answer. When Kai was 9 weeks old we soon found out that he would stop crying as soon as we picked him up!! so we went cold turkeyish. We put him down tired but awake so that if he woke up he would not be thrown by being somewhere different. We settled him in the cot by not talking but giving lots of strokes. we did this alot and we left him to cry for 5mins then 10 and so on.
have u tried puttig him in there for naps? using thr room for play and dressimg?
good luck, you will have to go through hell but think long term and know that he is ok.
