The amount of sexual abuse on kids we hear now is horrifying. Pls teach your kids about it. It's not a shame to talk about such things. They will not tell you anything if you don't open this topic with them. Teach them that NO ONE has the right to touch those private places, not even mama. And you shouldn't touch it as well. Just to show them how private these parts are. Teach them how to clean themselves. And everyday when they come back from school or when they visit someone, ask them whether someone has touched them anywhere. Keep asking them regularly. Put in their mind that it is a serious issue and they need to run to mama and say everything if something happens. Prevention is better than cure!
