This is a very, short story from a collection titled Uninvited Ghosts and Other Stories. It's playful and sweet, and slightly tongue-in-cheek.
Marian and Simon Brown have moved into a new house with their parents, and the family is so worn out they all troop off to bed, which is when the first ghost arrives from out of the chest of drawers. The children order it to leave, but it argues that it's lived there longer than they and so has precedence! The next night, there are two ghosts and the third night, three ghosts along with a ghost dog which has ghost fleas and scares the cat!
The ghosts won't leave. The children get a chance to visit with their well off Uncle who has a beautiful home and a nice TV, and they lure the ghosts into taking a trip with them but the ghosts won't stay. They prefer to be around children, and that wouldn't be so bad if they didn't appear out of nowhere and try to help with homework, or sit on top pf the TV, dangling their legs in front of it, or if one of them didn't suck peppermints and leave the smell lingering so their parents thought the children were sneaking candy into bed!
Fortunately the whole thing is resolved as the ghosts fall in love with a neighbor's noisy newborns, both of which calm down considerably when the ghosts begin paying them attention. eventually, Marian and Simon manage to persuade the ghosts to move a few doors away to the neighbor's house, where the children are pacified and peace and quiet reigns in the Brown house! This story was gorgeous and delightful, and I recommend it.
Penelope Lively has written about thirty children's books and a host of adult novels as well, so no doubt there is much more to mine there.
