Old children's book - title?
I'm looking for a children's book from my childhood, I'm 26, so probably from the 80s. Unfortunately I cannot remember the title. I live in the U.K. The story is about a rabbit who decides to move out because she has a lot of brothers and sisters. She moves into a little house and does it up and plants seeds in the garden. She has a collection of shells. She makes a friend called Martha? She finds an isolated brook and fishes and swims but her brothers and sisters soon join her. It has lovely illustrations, and I would love to find it, can anyone help me please? X
