He doesn't want to wear nappies.
He seems to get stroppy with pants (round the legs).
I've got it in my head that he liked a pair of boxers we had from Psycho, but I can't find the things
So, teeny tiny boxers? Preferably with characters on so he has more incentive to wear the bloody things (Diego would be fabulous!).
Any suggestions? Asda said they do that small... but have none.
