Alfie still hasn't had his MMR either Geo, just avoid babies with red dots on their faces. 
I'll have to phone the HV tomorrow to see if they can fit him in, he's had a cold, but I think he's over it. I, on the other hand, have had a stinker and it's in my sinuses now, so I can just about remember which number comes after five, eight isn't it? 
I have been watching Alfie like a hawk, to see if he exhibits signs of needing the potty. So far the only signs are that the carpet is wet or there is a funny smell.
He does go a bit glazed and stop whatever he is doing for a pee or poop, and he kind of grunts for both, but more for poops. Oh and he keeps grabbing his peepee when he needs a wee.
I definately think there is an element of timing, like after meals, when he has had a nap etc.. I think most babies can peep when they wake up, so working on that basis I started his brek and he was holding his peepee, then he started to peep on my foot. Aaaah! He stopped, and I put him on the potty and went psssss, and he did a peepee on the potty. 
Then after his nap, I put on the TV and he sat on his potty for ages, and after there was a peepee in the potty, and on the floor a bit. 
I'm so pleased with him for sitting and peeping, it's ridiculous.
Isla'smummy, Alfie has had the potty for a while now, he hated it for a while as well, but I sat him on it with his nappy on, when I knew he was tired and let him watch cbeebies.
Kath, that Moley is a clever little boy, bringing you his nappy.
I'm going to order an EC book, so I can get more of an idea of what I'm doing. 
How's the job hunting going Biglips? Is your partner working? Mine's a Phd student and still writing up, but he's looking for something as well now.
