DD is only child so far and is usually totally lovely when she's on her own. Often - though not always - gets into a right old state when it comes to playing with others. At nursery will often say to me she's going to play on her own, though actually regularly plays with other children. At home when have children over can start OK but then she has a meltdown, refusing to share any toys, calling them names and saying she doesn't like them. Makes me feel so terrible I do freeze up a bit and don't know what to do.
