Hello,
Our family is Muslim, and I shared your question with several other Muslim mothers as well. I didn't find consensus among these mothers with regard to children and fasting. Some felt that children under age 5 should not fast, others thought it was good to let them try to fast. I suggest talking to your child's pediatrician and your imam about this, to learn more about the physical health and spiritual aspects of this decision.
Personally, we have not yet required our daughter to fast. She is eight, and attending public school in the U.S. There is extensive scientific evidence proving the importance of nutrition to learning. It is also very hot right now, and easy for children to dehydrate during recess or lunch playtime. While we understand the significance of this very important observance for Muslims, we are not forcing our daughter to fast during school.
However, we do read the Qur'an and pray with her, and explain (and demonstrate) what Ramadan and being Muslim means. We also got a book from the library that you may also wish to share with your daughter, "My First Ramadan," by Karen Katz. We also encourage our daughter to volunteer to help others, and to be kind and respectful. We regularly remind her of how blessed we are, and how there are many people around the world who struggle to eat, gain access to clean drinking water, and survive extreme natural and societal conditions with few to no resources. So while she may not yet be participating in the fasting, she is definitely learning the values of Islam and the spirit of Ramadan.
Below are some additional resources on this topic. I hope this helps!
