I absolutely think 2 are better than one. Darcy and Lizzie play together all the time. He has a small issue with sharing toys! He will lie on the couch with his head hanging over, watching her play with a toy, and the minute she looks sideways - he's down and on it - she will chase him but never get angry with him! He used to lie on the back of the couch when I was sitting at night watching TV, but now he lies right beside me and she lies right behind me on the back of the couch!! She loves him, but loves me too - I get lots of kisses from her and he just likes to be beside me or on my knees!! I work in the summer, and I am soooo happy they have each other
