Is it possible

I really want to have a girl next and I know there are some old wives tales on it. I would like to hear some weather they work or not I’m just curious. I’ve heard that a lot of dairy changes the ph balance makes it better for conceiving a girl but I’m lactose intolerant so wanna see other options 😂 just for fun. Obviously I’ll be over the moon if I get another beautiful baby boy but 🤷🏻‍♀️
