Encourage your child to go to a baby shower dressed as their favorite star. Of course, you can simply dress your child beautifully, or you can dress him up like a rock star, a movie star, a TV or sports star. If you are throwing a party, then stick to the chosen theme - with appropriate decorations on the table, posters, videos, music and games.
For example, you can organize a parade of stars so that dressed-up children march in a circle to cheerful music. You might want to take a snapshot of each star so the kids can place their star photo in a homemade gold-edged frame.
You can also select different clothes and other props for such a holiday in advance and put them in a box so that the children at the holiday can choose their own stellar outfit - long capes, hats, feathers, any pieces of material and other things. While the kids are working on their costumes, you can help them paint their faces.
