We may be going on holiday in September and I have a dilemma, should I potty train DS before or after the holidays?. He seems to be ready for the potty but the idea of "Mummy I need to wee now!" in the middle of the motorway or while waiting in the very long queues of some popular holiday atractions just makes me wonder if it's better for the three of us to wait until we came back from the holiday. Any opinions?
