Best thing I ever did! They keep each other company...they play, and just totally love each other! It's great! And less work Id say....instead of getting into things they have curbed curiosity because they have each other! Seriously the best thing I ever did! I was scared cuz Bella was and only child, high maintainence, and the princess of all.....but she was very accepting of Diggy once she realized he is here to stay. Now they cannot be apart!
