Welcome to the world little Giles. 
I too loved Strictly. The standard was pretty high last night. Can't wait to see if the theme tune still has the same mesmerising effect on ds. Last year he would literally stop whatever he was doing and gaze adoringly at the sequins. And then revert back to whatever he was doing when Brucie appeared. OMG just realised I used to have a pause button 
The larger nappies appear to have done the trick (either that or he pooped and peed so well on thursday he was simply empty yesterday)
We're only getting up now, but last night was the worst I can remember. DS went to bed reasonably happily at about 7.30. Woke at 11ish. Dh went to him as normal, changed his nappy, gave him a cuddle, calmed him down etc. But when he left the room a tantrum commenced.
Anyone else had this? Full on tantrum, throwing himself aroumd his cot, sticking his arms up then ducking out of the way when you try to pick him up.
I tried being calm, telling him it was time to sleep, offering the simple choice of a cuddle in the chair or lyinig down in bed.
I ended up sat on the floor sobbing myself. Which stopped him momentarily. But then he started screaming again. I was with him until
- Then we had to swap as dd wanted a feed.
No idea how long dh was with him, but he woke again at 5. dh bought him in with us (we are going to need a king sized bed!) and he was still screaming. 
dh kept saying he was going to put him back in his cot but not actually doing it so I said we needed to just disengage which did work I guess, but took forever and no doubt woke all the neighbours.
I'm not even sure what I'm asking really. Just tell me this is going to get better? I never for one second thought the 21mo would be more disruptive than the 7wo
