Need some help - bathroom deco's for kids

I would go with little bits and bobs you can swap easily, nothing that is permanent or you'll be doing this all over again.

Why not get each of the kids to draw or paint some pictures of things you would like in there and frame them? Or go with themed linen etc.

I have stunning Teal towels and some lovely fuschia towels. I think they came from either Bed Bath and Table or Adairs, but I've had them for about 3 years now. Even Target can have some good colours, you just have to keep hunting till you get the perfect ones.
