After originally considering a story about two gay fathers, the pair decided the subject of two men raising a family had already been done on television and began to instead consider a story about two women. When asked about the concept of two lesbian mothers raising a blended family, Bredeweg stated, "We realized that there was a kind of a vacuum when it came to stories about women raising families. So we set off in that direction. Many of our own friends are moms raising biological kids. Some of them have fostered and adopted.
