I never thought about it but yea they probably do love up on each other all day and then when I get home go crazy
They are in the same excercise pen and I've never had a problem, what munchkins!
Simon and Hallie have never had an intentional injury. I had a trainer tell me that they will argue but will stop before it gets too far and I've found that to always be the case. I can never tell who starts it with my 2 either. My guess is Hallie but Simon is always the one on top with her pinned to the ground. I only get scared when I hear them screaming at each other which isn't often, most of the time they are playing/wrestling.
