We are in the middle of potty training and having mixed success. We started with pull ups but are now weaning DD off of these and moving to normal pants. The problem is we have a holiday coming up with a possible 5 hour + car journey. It's likely DD will fall asleep in the car. Is it best to put pull ups back on for the journey? I don't want to send her mixed messages as she thinks it's ok to toilet in pull ups...
