Never heard of anything like this tbh, my best buddy got a son in April and he and his gf are incredibly happy, seeing them, I almost, just almost wish me and my gf had a kid of our own :P
Not that time yet though!
Anyways my cousin got 2 boys as well, I've never heard her complain about anything like this, another cousin got 1 boy and I've never heard her talk about things like this either.
