We've been having a bit of a sleep-related nightmare with our cot-dodging 10 month old recently and despite doing my best to avoid co-sleeping it's looking like that's going to be the only way any of us get any sleep for a while. I'm not wild about it and would really like to know how long people have tended to co-sleep for and how they knew they could stop - do I try him out in his cot for a week or so every now and again just to see, or are there signs we can look for?
