The series of children's books "Katie Morag" are suitable for families w new siblings, daughters, or children w grandparents on the scene. That covers most kids... the rural setting is great (the Isle of Struay, based on the real Isle of Coll off the west coast of Scotland). There was supposed to be an animated series as well, but it seems to have fallen off the face of the earth. More info at the clunky publisher's site
