Any recommendations? We will be going on a road trip when we go to India, and chances are excellent DD will not pee in the toilets on the way (generally, way beyond disgusting), or behind some shrub/tree (plentiful, but she will only potty in bathrooms). She can't hold it 10 hours at a time, so lots of misery all around, I'm sure. So, I'm thinking of taking something with me that folds flat and can be used by her. Any recommendations? She is 4, so about 40" tall, and 33 lbs.
