Yay! Is it sad that this has made me REALLY happy?
Does that mean they will revisit the aibu about woman who gave her a baby grow?

Congratulations to the couple 
Just heard on fb this. Apparently sky news are reporting it too so it must be true . Very happy for them, but poor Kate with extreme ms <nods in understanding>
It's on the bbc too. Poor Kate. Lovely news but she'll feel like death warmed up at the moment.
So pleased for them, I'm such a royalist hoorah!

HG is terrible, and she's so thin to begin with - I had HG with DS2 and lost 2 stone, it was awful.
