Guessing genders is a bit ridic, amiright?!?

I can't possibly be the only person who thinks these old wives tales about guessing the gender of the baby are super silly. Whether it's the Ramsey theory (however it's spelled) or basing it off the shape of the woman's belly. If it were that easy, we wouldn't even need ultrasounds. Your belly is high, congratulations it's a girl!!!! Your belly is round, congratulations it's a boy!!!! The baby is on the bottom close to the vaginal entrance, it's a girl and a boy! Made that last one up, obviously haha!! My belly is high and I'm having a boy so..... clearly that is wrong. I hope I don't hurt anyone's feelings out there but it really does blow my mind. I seen a lady post "don't know what I'm having, can you guys guess based on my belly?" And she literally wasn't even showing yet and women were commenting "oh definitely a girl! Oh it has to be a boy".. I mean regardless, there's a 50/50 chance anyway right 😆. What's the silliest theory you've heard!?!? I'm dying to hear!
