When we would take our greys on vacation, my little blue girl would NOT eat. One night we went out for dinner with friends and my friend sent her sweet potato with us to see if Berry would eat that. Well, put it this way, from that point on, every time we went on vacation we had to bring sweet potatoes, butter, brown sugar and cinnamon (because heaven forbid she got PLAIN sweet potato!) with us to microwave and put in her food! She would just dive into it. Just a thought on what worked for us.
