Inspired by a few threads I've seen recently, and real life experiences, I'm just interested in sibling dynamics. People who have a girl and a boy, do you find they spent a lot of time fighting and arguing? People with two of the same sex, do they also spend most of their time fighting or do they get on better? We have two boys (4 and 7) who get on really well, independently play together for long periods of time and, aside from occasional hitting or shouting, don't really fight. They share the same toys and interests, and I would say they are really good friends.
Stories I've seen online and from friends who have a boy and a girl suggest that they fight a lot more and just generally don't get on. I grew up with a brother and we fought a normal amount but just didn't have that much in common. Different interests, friends and toys right from the start. There's a lot of love there of course, but not that much common ground for much of our childhood.
Would you say this holds up for you?
