Toddler nightmares - any suggestions?

[RoLoh]

Dd turned 2 a couple of weeks ago and in the last week has started waking six times a night with bad dreams. I think she's been unsettled as she moved up into a new room at nursery and we took her dummy away. Still I don't know how to handle it. I always had nightmares as a child and I want to spare dd (and me/dh) the same problems.

Can anyone offer advice? Thanks
