To make homemade food for a Baby Alive doll, mix 3 tablespoons of baking soda and 3 tablespoons of water in a bowl, add 3 drops of food coloring to the mixture, and stir until the contents are fully blended and creamy. Add 3 teaspoons of salt to the food as a preservative.
Alternatively, use the ratio of 3 parts baking soda to 1 part water to create a larger, thicker batch of homemade Baby Alive food. Divide the food into several portions, and add food coloring as desired. Store the food in an airtight container in the refrigerator to extend its shelf life. To create Baby Alive orange juice, add several drops of yellow and red food coloring to plain water. To create apple juice, add yellow food coloring to water.
Consider storing the Baby Alive doll food in recycled bottles and food containers. Clean the containers thoroughly before use, and create homemade labels to resemble actual baby food packaging. Measure carefully when adding baking soda, as too much causes the food to clog inside the doll. To rinse out a clogged Baby Alive doll, pour apple cider vinegar down the mouth, remove the baking soda sediment from the back, and rinse the doll thoroughly with water.
