My boyfriend had 2 boys before, and now we are hving a girl. His oldest brother has 1 little girl. His youngest brother had a boy, then a girl. So i dont think it proves anything
My one sister has boy,boy,boy, twin girls
My other sister so far has 2 girls
And I so far have 2 boys
But my dad had 3 girls, my one uncle had 3 boys, and my other uncle had 2 girls 1 boy
So now its a competition between my one sister and I to see which one will have the opposite gender (for some reason we just assume that we will follow the last generations pattern)
Thats all just a myth. It all depends on what the male gives you. (:
