Here's a comment I left on Julia's blog. She was concerned her four year old was taking a liking to lipstick and tiarras. (Here There Be Hippogriffs - Bender http://julia.typepad.com/julia/2007/02/bender.html Jenny left a nasty comment about how could she not force Patrick to comform, and soemthing about Julia's struggles for a second child being wrong if she considers tiarras appropriate for a boy. )
My six year old girl likes to wear dresses, in the winter, in Michigan, to school. We compromise, and she wears pants under the dress, and looks very nice. (Dress is short enough not to be a problem for gym.)
I put my two year old boy in a dress sometimes, just for giggles, and of course pictures. Especially if Daddy didn't want to change that last diaper. I think that by denying little things, they become big things. Unless you make a big deal of it most phases will pass.
Notice how Jenny didn't link to her blog? Can you imagine how many new visitors she would have, and the helpful comments we might have left?
