Yesterday we had to go out of town for about 9 hours. I put Darwin and Mabel in the kitchen so when they made messes it would be easier to clean up. Talk about being shocked - not even one mess - couldn't believe it. I have left them for six hours without any problems a couple of times but this time was so much longer. I'm usually at home with them during the day so they are walked regularly. Darwin is almost two and Mabel is just over ten months - there have been only three messes in about 5 months - they have definitely got it figured out!! Just had to share!
