Hi Irishconn
You're having a hard time, hey? I really feel for you - DS was exactly the same when he was the same age. Until 3 weeks ago, he would only sleep when held and it was nearly impossible to put him down. We've been working through the steps in "the no-cry sleep solution" and honestly, it really works. We can now put him down awake in his cot and, with a bit of help, he will sleep. Hopefully in a few more weeks he won't need much more help.

The other suggestions are really good too - raising the end of the cot & wrapping helped our DS lots too. Also patting his chest & 'shhhh'ing helps.

I hope some of these ideas help you both to get some sleep.
