Yep, you gotta be comfy when you lie down there next to them... they can sense your vibes... if you are not relaxed they can tell LOL another trick is to breath a little bit more audibly than you usually do... and make it get deeper and slower like it does when you go to sleep. I've heard they get in sync with this and it can help them go to sleep better. So basically pretend that you're drifting off to sleep.

I still sleep with the radio on... BBC News Radio... lovely droney soporific monologue... no sudden heavy metal... or worse still: Jazz!
