DD started potty training at the end of Feb, was out of nappies and into pants very quickly although did have a brief 'relapse', (but I think this was really an emotional response related to her baby sister). She does have the odd accident and still wears nappies at night, but is pretty reliably dry during the day, is happy using either a potty or a loo with trainer seat, and definitely is able to wait for at least 10mins from first needing a wee to reaching a loo.
We are going on a longish car journey (London to Leicester, so a couple of hours) in a fortnight. DP wants to put her in a nappy, I think that's a bad idea. What do/would you do?
