Girls like pink/dolls and boys like blue/cars?
Personally I do not believe in color or toy differentiation/obligation. Aaradhya wears every color in the rainbow including blue and her nursery is filled with all colors. She loves playing with her trains and bike. Kids are beautiful little people they should wear/play with every color and every type of toy. Their imagination builds their brain and that's how they choose their careers ahead. The boy who played with dolls might become a Milan fashion designer someday and the gal who loved cars might become a Formula one car racer. Let our kids blossom in what they love and enjoy the most. Happy hearts make happy homes :)
