Tell retailers what you're not happy about. You can do this in-store, online via email or try the company on social media.
From our experience, retailers vary vastly on what they are either prepared to comment or take action on. Some are very responsive, so it's always worth trying. The more people who complain, the more likely change will take place.
You can find a list of contact details for specific retailers here.
Gender stereotyping is big business, with pink clothes outselling other colours by up to 75%. Have we reached pink-saturation point? Maybe, but while there's a market for the idea that "pink is for girls" then retailers will keep selling it.
Take your money to retailers getting it right, or the ones you feel are listening to your concerns.
Talk to children about gender stereotypes and why clothes are split into boys/girls.
I tell my kids they can choose between sections and should ignore the signage, but it's not always easy. There is no quick fix, and ultimately, kids just want to fit in.
Social media platforms like Facebook and Twitter are a great way of raising awareness about why gender stereotyping kids is a problem. Some retailers are really social media savvy and are keen to help customers who raise concerns.
