Children at this age really don't drink tea. Instead, you can serve apple juice, apple cider or other beverages that LOOK like tea. But do so using a tea pot.
Food is easy! You can serve small finger sandwiches made with white, wheat or both breads. Fill them with egg, ham or chicken salads; another would be a little cream cheese with thinly sliced cucumbers; another could be turkey with swiss. Make sure you make the sandwich first. Then you trim off the crust and cut into either 2 or 4 triangles.
You can also serve small sweets like mini muffins, fancy cookies, teddy grahams or fun shaped marshmallows.
Serve fresh fruit like small cuts of strawberries, bananas, orange wheels, apple wedges, melon, kiwi, blueberries and grapes.
Use paper doillies to make it more festive and place different foods in fun and colorful dishes or fancy frilly ones. Make sure to have matching napkins, plates, cups and pretty table covers. Ask your guests to get dressed up for afternoon tea. If you find the tea cups you're looking for and still want to gift them to guests, make sure you've cut enough plastic wrap and ribbon ahead of time to go along with each.
Remember to have kid friendly music, such as cd's and a radio ready. Have a few games and small prizes. And make sure you have enough seating for all your guests. Be prepared for inclement weather if you're having your party outside.
Have a great time! And remember your camera!!
