Sam Vole and His Brothers by Martin Waddell

Sam Vole wants to do something all on his own, but wherever he goes, his big brothers go too. He goes collecting grass – but Arthur and Henry go with him and they collect far more grass than he does. He goes collecting nuts, and daisies, and he always has the same problem. So, one morning, very early, he sneaks out to go voling on his own. Without his brothers he hopes to have lots of fun, but he suddenly finds that he misses his brothers. Fortunately, they soon turn up and they all have a great time voling together.
