DS is mostly but not fully toilet trained - fine at home and his old nursery, not 100% when out and about. He seems to have recently started to become very funny about using public toilets - try to hold on for several hours, and then today he told me he needed a wee, wouldn't use the library toilet (which OK was a bit smelly), wouldn't use the Asda toilet and asked for a nappy. As I didn't have one, I said no , and just asked him again if needed the toilet. Then naturally ten minutes later, he peed himself.
Should I start taking a potty around for when we are out to avoid him going back into nappies when out, or should I just try and ride the phase out? Any advice gratefully received, and apologies if you all think it is a normal young child thing and so inappropriately posted here.
