OK it's probably too early to get smug, but he was in the garden all day today, running around with no clothes on as it was so warm, so I got the potty out and gently suggested he used it. For the rest of the day he did all his wees (about 12!) and poos (3) in it, without any prompting. No accidents, no fuss although he was quite pleased with himself.
He's 23 months and although I was vaguely thinking we might try training this summer I wasn't prepared for him doing so well at the first attempt!
So...what now? Is it likely to be a one-off or do I need to stop using daytime nappies outright now? what does he wear instead? do I need to buy absorbent pads for the car seat? travel potties? I'm clueless.
