Koko noticed my new shoe this morning. I just bought it yesterday at Croc's warehouse.
Koko: Mummy, I saw your new shoes.
Me: Yes, what color is mummy's shoes?
Koko: Pink.
Me: Har?
Koko: Pink at the bottom. (drawing a circle with his finger)
Koko is a big fan of 'pink'. If for him to choose his own shoes, he will go for pink. Unfortunately, color does differentiate the gender.
