I have a 2yrold DS1 and a 7 week old premature baby DS2, who is still in hospital, and will be for approximately another month. DS1 has just today decided that he is ready for potty training, and he is doing rather well at the moment. The only problem is, we will be going to see his brother every day, and it takes an hour to get there on the bus. How should I go about potty training him during this time? Many thanks.
