Never having had boys I'm hardly an expert but... I love those stickers that you can put in the toilet or potty to help boys aim. My girlfriend told me that she put a ping-pong ball in the toilet and her boys aimed at that for a while (until the dog saw it!)...

I think some super sensitive kids that don't like the feel of nappies or wetness around them can easily toilet train at this age. And boy was I glad to get my second one out of nappies early. *yay* jojo
