Yay for baby-tiddley! Brilliant, brilliant news! Pleeeease stay with us! All being well, mine will be Feb babies too but I'm not going anywhere 
Sheldon, my MW gave me the maternity exemption form at the first appt not that I've sent it off yet
You lot are fantastic. I went to bed for an hour feeling really despondent and you've so cheered me up! I think I was just a bit extra freaked out because she tried sooo hard to find it and didn't (I think) make eye contact with me again after that (tho that could be me being hormonally paranoid), even though I was waffling on about 'oh well hopefully it's not a double MMC!' etc. There was no problem hearing the heartbeats at the scan, but perhaps that machine - being so much more powerful - is just better than the hand-held machine, like you say, JoJo?
Also, although she was perfectly lovely again, I got the sense that in a way she signed off on me a bit: apparently because it's my first birth and twins, and the other 'high risk' factors which have to be assessed, the likelihood of a natural birth in the MLU is very low and there's a high chance it will be a c-section. Which is fine, but she kept saying, oh, ask your consultant about this and that, and suddenly it seemed as if everything was going to be more medicalised than before. But two healthy babies is the most important thing.
Anyway, thank you so much. I feel better hearing your encouragements and advice. Really, thanks.
