I have two daughters, ages 5 and 6, so when we choose shows involving superheroes to watch together, those shows usually involve female superheroes. They connect with them better, and honestly, I like them seeing girls be the strong ones for once. Mysticons is one of our favorite shows, which you can watch on Nickelodeon. It has been on for about 6 months and in that time has become a huge hit with us! Even my husband enjoys it!
