Mitya and allergies. Fairy tale to read with parents

An inquisitive boy, Mitya, secretly ate chocolate and nuts from his mother. He started having allergies. He, of course, didn’t know at all what it was and why he couldn’t eat certain foods. But mom and dad were not at a loss and came up with a way to explain what happened in a playful way and calm their baby down. Mitya liked the fun game so much that he very quickly learned the basic rules and realized that allergies are not at all scary.
At the end of the book, useful recommendations for parents from allergists and immunologists are presented.
