Co-parenting sites offer a useful service by connecting people who want to raise children together. But not everyone is in favor of such websites. Many religious conservatives, for example, believe such sites are damaging to the traditional family.

Many people hope to become parents. But for some people this dream is harder to achieve - including for those who haven’t found the right partner, or who are infertile or homosexual. Internet platforms such as modamily.com and familyship.org help connect potential co-parents with one another. The co-parents are then not romantic partners, but friends.
