Tea set for children (Bellevue EH7)

I have a small teapot (simple, white) and was thinking it would make a lovely present for my young cousins if i could add some small cups and saucers so that they could play at having tea parties. The older will be 7 this year. I would prefer the cups to be white but I'm not fussy. They don't need to be similar either. Thanks in advance.
