this is a mods as make so the kids can be werewolf, the mods is not perfekt, and the children don´t make all of werewolf abilities, but the children can Digging in the ground, Sleeping on the floor and Transformed into a werewolf shape.
therefore this mods not is perfect I recommend that you take an adult sim, and add the werewolf abilities that work first, and then make the sim a child, then the child will be able to perform these abilities,
