Not only does it say that they grow out of it (phew!), but one of the comments also usefully noted that there is no problem with being a princess, as long as you are an independent, empowered, driven, fulfilled one ... and I guess this is the key lesson to remind children of. It is about marrying someone who helps you fulfil your dreams, not just who pays off your credit card and can keep you in a castle.
This all harks back to thinking about our baby being a girl. Of course now I do dress her in pink, as all babies look androgynous!!
