I read this novel in 1963 or 1964. A little girl is left to live with a childless couple in an apartment building, because her father goes away for work. The other children in the building talk about her among themselves, thinking she is like a snooty princess. But no, she is a very lonely little girl, and has only one possession, a doll. There is a broken wagon, and the children become friends with the girl when they all work together to repair the wagon. The wagon is a bed for the doll and it is given to the girl to take with her when her father returns.
