20True: "Crying" Is Inaccurate Until Three Weeks Post-Birth
This is more of a technicality rather than a myth that's true, simply because of the word "cry". It's obviously a well-known fact that babies make a lot of noise during their first week they're born, but this can't technically be called crying, because babies physically can't cry during the
first three weeks of their life. The reasoning behind this is a delay in tear duct development and it's completely normal. While a baby can produce enough moisture to ensure that their eyes are well-watered and protected, they simply can't produce enough tears to physically cry until around the three-week mark. This is why instead, they'll yell and wail rather than full-on cry.
