Child in the first degree

The concept of child refers to the direct line of descent of a person, whose parentage has been legally recognized, whether biological (natural) or adoptive .

As for the degree of kinship, it is calculated by counting the number of generations between person and their descendant, then adding 1.

So Mr. "X"'s son would be his child in the 1st degree, while his grandson would be his child in the 2nd degree, and so on.

In summary, the expression "all my children in the first degree" means any person of whom a person is legally the father or mother , including any child adopted according to the law.
