Question:
Is it permitted for children to color for fun, or to use activity books where they stick on stickers on Chol Hamoed?
Answer:
Hello,
Children may color in an activity book or stick on stickers during chol hamoed. The reason is because it is considered tzorech hamoed, as it is a festive enjoyment, and it isn’t a maaseh uman ( a professional act). An artist however would not be allowed to just draw a painting on Chol Hamoed, because it is a maaseh uman.
