We like the idea of thinking small, especially for a small child's birthday party. Start with miniature invitations. The smallest envelope the post office will accept is 5 inches long by 3.5 inches high, but if you hand out invitations personally, you can make them even smaller. Young children love the idea of ordinary objects rendered in miniature. Fairy and dollhouse motifs are a natural here, as are small dolls, tiny books, miniature trains, sports cars, and tea party cups and saucers.
Make single serving cakes in large cupcake tins, or try our cute Birthday Cake Cookies. For an overall design, use polka dots. They're small but have great energy. Polka dot wrapping paper and party supplies are readily available and work well with a tiny treasures theme. They also coordinate nicely with solids and stripes. It may be a small world after all, but it'll be just the right size for your young child's birthday. Just be sure to avoid items that may present a choking hazard for very young children.
