Did you notice this bit of the article:
So she managed to have an upbringing that didn't conform with gender stereotypes without being brought up gender neutral... so why go to such extremes with your own son? It isn't even logical. Her 'experiment' would have made more sense if she'd said "as a child I was forced to wear pink and told I couldn't be a fire fighter".Miss Laxton said her own background had influenced her view about gender stereotypes.
‘My mother’s very sporty and my dad was very emotional. We’d watch The Wizard of Oz and always start crying, whereas my mum would think we were really soppy,’ she said. ‘So it’s always seemed obvious to me that stereotypes didn’t fit the people I knew.’
Also, if you are going to use your child as an experiment, at least think through your methods a little better. It seems to me that the early baby to preschool years, at home and at the park with friends, are relatively gender neutral, with lots of craft activities, ball games, scooters, primary coloured toys. At that age, kids don't conform to gender stereotypes much if you don't push it with them. AFTER 5 is when the unhealthy gender stereotypes kick in, and kids are influenced more by society through the playground than their home environment. Revealing the boys gender now leaves him wide open to all the peer pressure at school, which will pretty much defeat their experiment, and screw the poor kid up for nothing!
