Thoughts?

So Friday my mom n law got my stepdaughter for the weekend, my stepdaughter called me and her dad and told us that a little boy touched her Gina “vagina” (she’s 4 years old) and we are livid her dad will be going up to the school and he also found out that since school has started his daughter has already missed 8 days and has a lot of tardiness. They live right across from the school! Her mom hasn’t told us about the touching incident I’m starting to think she doesn’t want to include my husband but as a father he has every right to go up to the school and raise hell doesn’t he? Smh cause I already know she’s gonna downplay everything but when I was her age I was touched by a little boy and was scared to tell so I don’t take it lightly either
