Second parent adoptions are essential in protecting the right on the non-biological parent in every case of same sex union, marriage or cohabitation and here’s why! One tenet of the debate surrounding same-sex marriage has focused on whether same-sex parents provide poorer conditions for raising children compared with different-sex parents. Political and public dialogue ensures that this notion remains pervasive and persuasive, even though the Supreme Court decision this summer ensured marriage equality in the U.S.

Second Parent Adoptions are Needed. . . And it isn’t just talk: Laws exist that implicitly reflect the rhetoric that somehow same-sex parents are different.

For example, even though same-sex couples make decisions together to have a child, and even if both parents appear on the birth certificate, the non-biological parent may have limited legal rights over the child. In Texas, two parents of the same sex are even prohibited from being listed on supplemental birth certificates, only allowing for parents where “one of whom must be a female, named as the mother, and the other of whom must be a male, named as the father.”

Although all states offer second parent adoption to same-sex parents in legally recognized unions, only 15 states and the District of Columbia offer second-parent adoption to same-sex parents in cohabiting relationships. This means that in cases where the parents are not married, the non-biological partner may be denied access to the children.

An underlying assumption about parents in same-sex couples seems to be that same-sex parents are less invested or are unable to follow through on the types of parenting that matter for children.

This type of argument is often rooted in the idea that biological parents who are partnered with each other have an advantage over a parent partnered with someone other than their child’s biological parent, with non-biological parents less likely to invest or commit to children who are not their “own.”

This is wrong and must stop! Second Parent Adoptions are Needed As Policies Against Same Sex Parenting Are Not Science Based

Laws and policies that undermine the rights of same-sex parents are more based on politics than on actual science of how they parent. Same-sex parents who conceive children via assisted reproductive technology, for example, should have the same parental rights as heterosexual parents who conceive via assisted reproductive technology and do not have to jump through the same legal hoop.

Very little research has directly tested whether there are different types of parenting investments by same-sex couples. However, in one study that we conducted, we found no difference in the amount of time parents spend with children between same-sex parents and different-sex mothers. But there is a catch.

Mothers in same-sex relationships, fathers in same-sex relationships and mothers in heterosexual relationships spent about the same amount of time in child-focused activities, about 100 minutes a day. Men in heterosexual relationships, however, spent significantly less child-focused time than all three other groups of parents — about 50 minutes per day. That means the only difference that we found tended to favor same-sex couples (and heterosexual mothers).

Importantly, these differences persisted when we controlled for factors that have well-known influences on time spent with children, including parent’s education, the number of children, the age of the children, and parent’s time spent working or commuting. Here’s the catch to this “no difference” conclusion. When combining estimates across mothers and fathers to look at time investments at the family level, not just by individual parents, children raised in same-sex families would receive an average of 3.5 hours of child-focused time a day, compared with 2.5 hours for children in heterosexual families.
