I hope F is ok, TSC! :( And C too. Sounds like you're having a bit of an awful time at the moment, I'll keep my fingers crossed for things to improve!
No counting here, DH. No talking yet either! Though we might almost be there... We're semi-reliably getting "Gaaah" with pointing at the cats, and there's been a lot of "Dada" while looking around over the last few days, whenever DH leaves the vicinity.
M seems to have abandoned most of her sign language, aside from "More!". We have a wooden advent calendar for her in the living room where each door gives a piece of Santa's Workshop, and a piece of chocolate. Now every time she enters the room she points at the calendar and signs "More!". 
For TV, M doesn't get any at nursery as far as I know, but she normally gets about 20-30 minutes in the evening when we get home, while DH and I run round prepping food/bath/bed stuff. At the weekend, it's sometimes just on in the background as we potter about, but she doesn't tend to sit and watch.
Have fun with the block building, WSS! :) M seems to have really embraced building towers here, I keep turning round to find she's stacked things one on top of another. Today it was toilet rolls, the day before was DVD cases...having pulled them all off the shelves.
She managed a tower of 7 blocks last weekend. I was
watching her carefully and methodically pile them up. Amusingly the tower was only built with blocks of red, green and yellow. The blue blocks were apparently not good enough for building with, and had all been thrown into the corner. 
She's a strange child!
