Parent educate your Ward (Child)

A little but concise sex education by moms (and even dads) matter.
Spend and spare some of your time with your kids and don't let their peers help you. Tell your young girl or boy what she or he needs to really know now before time runs against you both. This should however depend on the development and exposure of your child or ward. Some children are now beginning to display adolescence at 8 or 9.
Be attentive to whatever opinion or question they'll raise. Don't be a regular scolder. This can chase them away.
And that is why many of them prefer opening up to their friends or nearest neighbours than you. Only a few wise ones will choose a matured adult like good teachers, church leaders, etc as confidants.
Save a whole generation, give the caution, not just the cure!
