We had a tea party for several four-year-olds in early September. This was a really easy, but fun, party to host.
We served two kinds of (caffeine-free) tea, sparkling pink lemonade, grapes, and lemon cupcakes with vanilla frosting, sprinkles, and maraschino cherries on top. The kids enjoyed their late-morning snack time on the deck, which was also a practical location in the likely event of spilled tea or lemonade. After they were done with the tea and snacks, the kids blew bubbles and played in the yard.
