Fasting can be a very rich experience if you fast with your family members, including your kids, as you do it together! Obviously, it may not be wise to ask small children to skip a meal as their bodies are still growing and developing. However, there are other ways children can learn the ritual of fasting.
Whatever you decide to do, it’s important to teach your children the practice of fasting is not just subtractive (giving something up), but also additive (adding something), so that they understand one of the purposes of fasting is to create space so we can “feast” on God, His Presence and His Word.
