Thankfully there are the once piece swimsuits around for kids with high sun protection and my son does wear one - but once again the boys ones are BLACK!!!!! A great colour to wear in the sun!
BRIGHT BOTS sell coloured sunsafe suits for boys that aren't black. They have their own website, or you can buy them IRL at stockists, such as the AntiCancer Council Shop in your state.
It is so hard to buy him toys that aren't spiderman, the HUlk or TMNT or Princesses and Dora. His favourite wiggles character is Dorothy Dinosaur but can I find him something that isn't blatantly "girly".
I have just had a daughter so I guess I am about to experience the flip side of the coin. She wears her brothers clothes and looks stunning in blue and green, and is often mistaken for a boy bcos she is blue or green.
I guess what I am trying to say is that as parents WE can sexualise and gender stereotype our children before society even gets to them.
We dress them, we begin their education every time we buy a toy, book, video or piece of clothing.
