The first time I travelled after the baby was born was my first week back at work.  I took a day trip to Houston and that was ROUGH. I had never pumped on an airplane or an airport bathroom / pumping lounge. I mean, heck, I had barely pumped period! In addition, I was still so physically exhausted at 3 months postpartum, that travelling / pumping / working / getting home late at night was exhausting.
