While I agree that your child is not you and FOSS doesn't need to be your child's value, it needs to be said that

FOSS is the software author's value. It correlates with the author's intentions, their incentive and the software's shape and influence on the user – your child. It's a way to delineate content you want your child to see and that which you don't (and thus we circle back to the idea that you imposing a policy ultimately means imposing your values anyway).
