I raised three girls, and I taught them the correct terminology since that's what they are called - biologically speaking. Americans seem so shy about referring to our body parts correctly, instead we'd rather assign derogatory or weird sounding names to our body parts. When parents do this, they are usually insecure about talking about the sexual side of the human body themselves, especially with their children. Would you be one of those parents by any chance?
How about telling your child that NO ONE should touch her privacy parts (chest, breast, butt, or anything in between) EXCEPT you - her mother. If gramma keeps her at her house, or babysits her, gramma can bathe her, but Grampa has NO rights to touch her as a female, even if Grampa is the greatest grampa on the face of the earth. As an incest survivor myself, I taught my three girls that NO MAN - not Daddy, not Grampa, not Uncle, not any male cousins, or anything male - could EVER touch their privacy parts (breast, chest, butt, vagina or vaginal area; nor are they to ever let them kiss them on the lips - no, not ever! Now, I know that in some cultures kissing on the lips is socially acceptable. I'm not speaking against anyone's culture here, but hopefully you all undertand the gest of what I mean here.
Mothers must get BOLD with teaching about the subject of molestation and incest events with their children. Educate them using the proper terminology, and so forth for their own protection when you aren't around. I can't emphasize this enough! Teach your children, and repeat what you teach until they are grown. They may forget as children what you say about this, so that's why it is important to re-iterate it often as they grow. Do it each year on their birthdays, as I did my kids. They MUST know!!! Teaching them this knowledge could save their life one day.
Children can handle far more than we give them credit for, especially when relating to their body parts that God made good, healthy, and for a healthy reason. Teach them HEALTH and they will prayerfully remember to treat their own health as a prize that shouldn't be opened by anyone but them one day - and NEVER against their will. I'd be happy to address any incest issues if anyone has any. Thanks!
