from their father, without these a son cannot bond with his father.
This is especially important so the son can identify with his father, so feel well comfortable and like the concept of masculinity and being masculine.
Getting a connection with your children:
▪doing with them what they want to do
▪spending the time with them
▪listening to what they have to say about what interests them
