This is something that I've just come to realise about Americans. Back home, little children would go naked on the beach and nobody would think for a moment about it. I remember stripping off as a child at friend's houses to play in sprinklers etc, and all the other kids did the same.
Now, I'm so shocked by the prudish way that so many American adults behave with their children. I found it particularly when in the South recently - I didnt realise it at the time, but apparently I shocked everyoen by letting my girls (one and three years old) strip off ready to get into their swimsuits at a park. They were both running around and I was chasing them with their swimsuits, but it didnt bother me in the slightest. If there had been other naked kids there, I"d have given up on the swimsuits altogether. But dh told me afterwards that what I did was shocking, letting them go naked as I sorted out the bags and sunscreen etc.
Here at home, they go naked all the time in the backgarden, and in the house. Dh has heart failure when they run out on the front porch or to the car naked, and ushers them in as if they are committing some act of indecency. It drives me nuts, and he has toned it down a little so at least they don't realise that it's an issue. But I wouldnt care a jot if they came out the front naked, I just don't get this puritanism about children. Ugh.
As for perverts, they are no more likely to eye up your child if he/she is naked than if he/she is in a swimsuit, imo. And some of the swimwear and clothing that parents put on their kids is far more provocative than going nude! That was what astounded me about my experience in the South when I let dds go naked - that there were other little girls in skimpy bikinis that I would not allow near my child. So, dressing your young daughter up sexily is fine, but letting her go naked is indecent.
I just don't get it!!
So, in our family, there are no two piece swimsuits and no short skirts, skimpy shirts, backless tops, or adult style clothes, but nudity is fine and dandy.
