Thanks for all your help girls. I finally found the perfect doll at a specialised toy shop It's a soft bodied doll made by Zaph Creations (same company as Baby Born) which is only a centimeter smaller than a Baby Born and therefore should be able to wear Baby Born clothes, etc too. It closes it's eyes and takes a bottle (which comes with it) and I've bought a dummy for it so it has more than enough accessories to keep DD happy.

Cheers again!
