Meg and Mog series by Helen Nicoll and Jan Pienkowski
Poppy Cat series by Lara Jones
Calm Down Borris by Sam Lloyd and Stella Gurney (they have other puppet books that are equally as good)
Owl Babies by Martin Waddell (if you look carefully you can find a Mummy and 3 baby owl set - my daughter's pre-school has this book as a story sack)
Winnie the Witch series by Valerie Thomas and Korky Paul
The Bog Baby by Jeanne Willis and Gwen Millward (they have other books which are equally as good too)
Five Minutes' Peace by Jill Murphy
Maisy series by Lucy Cousins (well, just about anything from Lucy Cousins is great)
Guess What I Found in Dragon Wood by Timothy Knapman and Gwen Millward
I think I've suggested enough.
