Catholic parents today often know little and so what they pass on to their kids is just an ethical sketch of Catholic morals and not much more.
Parents, educate yourselves so as to teach your kids. Your kids will not be taught catechesis at school or day-care or anywhere else. Pray for the grace that you can start to teach yourself first principles of the Faith.
There is a practical but also an objectively guaranteed right way through the confusion of opinions and hypotheses and if you don't teach your kids the way (this is your job) then no one else will (it is your responsibility).
