Yep yep yep has been 13 months straight of co sleeping with DS2, didnt co sleep much with DS1.

I wake up in agony every day in neck and sholders. DS2 is a very restless sleeper and has to be touching me!!!

DH sleeps with head at opposite end of bed to give me some more room with DS2 but I am still sore, but not as much as I was in early days or maybe I am just used to the agony now!

Good luck
