I have good news to report.
A shitty bedtime was had, despite putting him to bed a little later tonight to make up for the late sleep this morning.
Every time I settled him rocking/patting etc. he would wake instantly the second I took my hands off him. He would just roll right over and stand up like a fucking meerkat. 
After the 4th repeat I was loosing my temper internally. I walked out the room, and shut the door. He was moaning, but not crying, kicking the shit out of the cot, trying to climb out (from the sound of him!) and generally sounding pissed off. I wouldn't say he was crying, but protesting more.
Anyway after 5 minutes of this, all went silent. I sat there and waited for ages. And then opened the door almost afraid to look... yep, he had gone the fuck to sleep! Himself! Wahooooooooooooo!
So, if he can do it tonight then he can sodding well do it every other night too
.
Rocking and patting does not make for a happy bedtime!
