Curse or coincidence?

Heather🐻
Since my older cousin was born, our whole family has either had a large group of girls or boys, never any mixing. I was born in a group of 5 girls, then my brother in a group of 6 boys, then my little cousins are all girls(8), and now I'm having the 4th boy in this recent group. Does anyone else think this is too crazy to just be a coincidence? It's always been insane to me. And this is on both my mom's & daddy's sides. What do you think?
