There's also a difference between modeling and pageants.
Jordan (my 9 yr old) does modeling, but what she is generally doing is modelling clothing that kids her age would wear. That is the whole purpose of advertising.
and yes she wears makeup for the photo-shoots, but she knows this is only done for those occasions, and it is done so that she does not look washed out on camera. Her finished image looks very natural, and I have pointed this out to her. Once again, advertisers don't want the kids looking like Jr. Dolly Partons - because that is not going to sell the clothing or other products that they are trying to promote.
The same goes for Michael and Seth- they also wear makeup on camera, but obviously it doesn't show in the end product.
