Who ever would have thought the toilet training of a two year old boy could so enthrall four adults? Me, my husband, adult son and the lodger (male aged 23) seem to have talked about little else for days. Every success (and there have been many) has been rewarded with Olympic style cheering, a sweetie (smartie or white chocolate button), a sticker - and, to the delight of the young man concerned, flushing and hand-washing rituals. I haven't had to mop up a single piddle puddle and even though he was out with the menfolk for the whole afternoon, he managed just fine. My husband did confess to being slightly embarrassed when, having assisted grandson to use a public loo (urinal), he was using the facilities himself when another bloke walked in; grandson was very interested in the proceedings and heartily congratulated my husband with, "Yay, good boy for doing a wee". 
A plug here for the Boy's Toilet Trainer we've been using: www.tippitoes.com/shop-by-product/potty-toilet/boy-s-toilet-trainer.html I only wish it had been around when my own sons were toddlers - my grandson absolutely loves it and I am certain it's why he has so quickly taken to using the 'big boy's toilet'.
