My 3 year old molested his dad. What are my options?

Answer 1

call the cops and report a sexual assault, obviously

Answer 2

What the other two people said.

Answer 3

You need to look at this with more suspicion. So what if a 3 year old strokes a parent's genitals in an accidental fashion? That's not molestation. Your husband or partner would have to allow and encourage this in order for it to be molestation, in which case the adult is the molester. Get real.
