Our beloved daughter, Zelda, is now three years old. And very conscious of the fact, too.
She has stopped wearing a nappy at night time, much to our delight. The whole process went quickly and smoothly after we forgot to put one on her one night recently. Since then we have not bothered, and she has only had one accident during the last ten days or so. The only down side to the story is that we had just bought a new packet of nappies (hardly the cheapest consumeable), which are now gathering dust in the bedroom.
Her speech has also developed, and I am of the opinion that she shifts between English and Swedish far more easily and often than Freya did at that age. Though I could be wrong, and I do not trust my memory.
