Clingy one year old.

I've heard that if you are having a girl and already have a boy that your boy will be clingy and lovey towards you and if you are having a boy he will be distant. Has anyone experienced this? Doctor's pretty positive im having a girl and my son has been all over me! Always wants me to hold him and gives me lots of kisses and hugs. Just curious if that has been true for other people. Not that any of these old wives tales matter but it's interesting to see what other people experienced.
