So, I just got my two little boys yesterday. For a good amount of the day, they were tumbling around, taking turns pinning each other down. One of them appears to have claimed the little hideout box, while the other one ends up sleeping on top of it or to the side. When they are wrestling, it looks rough to me, but there has only been squealing a few times (and not very loud at that). They also wrestle around and then get distracted and don't seem to mind realizing that they are near each other. I guess I'm just wondering if this is how young boys play or are they trying to figure out who is dominant? Also, how do I know if they are fighting? This may be silly, but I feel kind of bad that one gets kicked out of the sleeping cave thing... is this something they most likely will get over once they figure out who is boss, or could it be possible that they are huge fans of each other?
