In a way that involves both parents.
The children were raised biparentally, with both their mother and father actively involved in their lives.
Biparentally → It is formed from "bi-" (meaning two) and "parent" (from Latin "parens", meaning father or mother) and the suffix "-ally" (meaning in a manner). The word "biparentally" refers to something that involves or is related to two parents.
Think of 'two' ('bi-') parents ('parent') acting 'in a manner' ('-ally') — that's why biparentally means involving two parents.
