My dd is nearly 3 and at home is as good as good and I would say potty trained - no accidents. Before we leave home to go out anywhere I ask dd if she needs the toilet to which she replies "No" - as soon as I am stuck in traffic or along a main road dd suddenly decides that she wants to go "Now" - which always results in her wetting herself !! Does anyone have any tips pleeeeeeeeease as I am getting desperate !!!
