Mom, where are your modesty shorts?

Some of the most invaluable lessons of life I learned while I was at college but not in college.  During the summer months, God often blessed me with nanny positions that helped pay the bills and taught me about the many facets of motherhood.
One concern parents often have is knowing when a child is old enough to learn certain information.  Parents often wonder when to expose their children to PG movies or when to tell them about the process of baby production.  One of the sweetest lessons I learned as a nanny was how to introduce the topic of modesty to your children.   
1 Tim 2:9-10 Likewise, I want women to adorn themselves with proper clothing, modestly and discreetly, not with braided hair and gold or pearls or costly garments, but rather by means of good works, as is proper for women making a claim to godliness. 
My guess is that if you introduced this concept of modesty to a young tot with a Bible verse, you are probably going to get a lot of blank stares.  However, that is not to say that the concept cannot be introduced. In fact, if you do not introduce modesty to your children (especially girls) at a young age, you are doing them a disservice.  Our culture is one which lifts up barely-there clothing and sexualizes children at a young age.  Think I am being too serious?  Then you haven't seen Toddlers & Tiaras on TV or anything on the Disney Channel.
As a nanny, I learned (through the mom and daughter I babysat for) to make modesty into a positive experience for your children rather than a negative one.  Instead of waiting until your child is 12 and yelling at them that, "You may not wear that!", you can make it into a positive and pleasing experience that honors the Lord when they are young.  These lessons will often produce positive fruit as your children ages into maturity.  The wise mom who indirectly taught me this would have her 3 year old daughter wear shorts under her dresses since 3 year olds tend to fling their legs any which way not realizing that they are flashing all those around them.
This 3 year old's mother had made it such a joy to wear modesty shorts, that her toddler would often inquire if other ladies of older ages were wearing their modesty shorts too.  She looked forward to honoring the Lord with her clothing.  I don't know about you, but I wish that were my attitude more often.
Certainly there are seasons in life and parents must be wise in when and where they will teach their children these important lessons of life.  But don't wait too long or before you know it she'll be 16 and wanting to dress like all those idiots on some show about liberated, angry, divorced women.  Modesty is a lesson to be learned in all seasons of life.      
Proverbs 31:25 Strength and dignity are her clothing, and she smiles at the future.
