Ds1 (3.6) has been invited to the birthday party of a girl from pre-school along with most of the rest of the class. All previous parties we've been to have been close friends of his/ours, but this one I only really know the mum by sight and know that her dd will be starting school at the same time as my ds.
What kind of pressie would be expected? I don't want to spend loads but really don't want to seem stingy either! is £5-£10 about right?
