Birthday party planning information:
If Teletubbies are among your child's favorite friends, you have many Colorful options for parties, with Dipsy, Tinky Winky, Laa-Laa, and Po.

Teletubbies decorations and party goods will be a major hit, but purple, yellow, green, and red can be carried out in other ways, too.

Cupcakes can be frosted in this manner: Dipsy cakes are green, with a straight line added with green icing; Tinky Winky cakes are purple, with a triangle; Laa Laa cakes are yellow with a curlicue; Po cupcakes are red, with a circle. (The same decorating concept will work for cookies; check out the Sugar Cookie recipes in "Cookies" page of What Works.)

Jello Jigglers are another colorful food possibility, in grape, cherry, lemon, and lime.
July and August? Bring on the Popsicles. (Just be super-cautious about those Sticks! This is a Sit-Down treat; in fact, all eating is safer sitting down.)

Sandwiches are a great party food. Geometric shapes can be created with a bread knife and various cookie cutters. Softened cream cheese may be tinted in colors, if you like, or left plain white.

Sandwiches may be prepared more simply, and just cut into 1/4's for easier handling, if desired.
Thin slices of Banana Bread, with cream cheese, also make a fine party food.

Other suggestions or comments:
Beanbags can be made of sturdy cloth, in the four colors, and tossed into a bucket or a coffee can, or just tossed up into the air or to a Parent partner, and caught, again and again. (If you have the time, you can make Extras, and send them home as parting gifts.) Have some Music going; Teletubbies CD, or any good kid-friendly tunes. While the music is going, you might also play with rhythm band instruments, or Dance. Scarves are good for dancing; the wispier and floatier, the better!

If you have the luxury of good weather and a nice yard, Play Balls (the inexpensive kind kids always see and Want, sometimes seen at the supermarket) can fill some time.
Likewise, Soap Bubbles are fun to chase, pop, and dance with.

Home-made play dough can be tinted with 3 same-flavor Kool Aid packets (unsweetened). Check the recipe in What Works "Recipes Kids Can Make": Kool Aid Play Dough.

Have you ever tried painting with Pudding? Or with Shaving Cream? (Add a little food coloring.) Or, you could just set up a table or an easel for a pre-school tempera painting party. Use large brushes, and/or sponges cut in geometric shapes.

Keep your camera close at hand!

The really Courageous party people with Helpers might want to try decorating T shirts or Hats with Acrylic paints. Geometric shapes are easily cut from sponges; "chunky" foam stamps from the craft store often include that curlicue shape (Laa-Laa). Put a sheet of aluminum foil inside each shirt to prevent paint from bleeding thru to the back of the shirt, and check the label of the paints to see whether Ironing is needed for color-fastness. Allow drying time; this would probably be an Early activity.

Allow some time for Simple quiet things like reading a Teletubbies board book, or just sitting on an old quilt and playing with blocks, indoors or out. The smallest children tend to engage in "parallel play" (side by side, and individualistic), vs. extended interaction w/peers, and there's absolutely nothin' wrong with that!
