I have been brought up with the belief not to walk over someone because it can stunt their growth. Can anyone else here say where they have also heard of this? If yeah, where is the source?
The Be'er Moshe 8:36 discusses this issue and says it is something that they used be makpid on not to step over a child and if they went over him they would ask the person to step over him the other way so he can grow to his full height.
The Be'er Moshe continues that this custom is considered among the custom of old women which the Rashba (Shu"t 1:69) wrote that we should not belittle even if we can not understand the reason, they are certainly established on "mountains of holliness".
