When his father goes away for a week, two weeks to even a month is a very long time for a child who is always close to parents, and once in a while this problem is very fatal for those who do not leave parents, I once found a child who is sick from being left behind by his father, and this is indeed a very bitter thing for the child. but will be very different from children who are always away with parents, even sometimes they will also be happy because there is no prohibition whatsoever.
