Does the nursing woman's husband become a father to the nursed child, and are all his children from other wives considered siblings to the child?

If a woman breastfeeds a child five times or more, and the milk is a result of intercourse with her current husband, then this husband becomes the father of the child through suckling (radāʿa), and all of his sons and daughters—whether from the breastfeeding wife or another wife—are considered siblings of the suckled child.
