Let us remember that NK herself never had kids.
People develop. Some love kids since childhood, babysit for kids, and may never have own kids yet love children. Some women never feel what “kids” are before they have their own. And I suspect NK belongs to the latter group.
She has a remote idea about CW's little girls. One wonders, however, if NK was attracted to CW because she felt he was a good father.
(Amber Frey used to be a party girl posing for nude photos. Being a single mom changed everything. In SP, AF saw a potential husband, but was cautious because she had a daughter. When SP stated he never wanted children and would rather have vasectomy, it raised her antennas. She started inquiring about SP with her friend, a policeman, because facts did not add up. Then she found out about Laci, his pregnant wife, and when compassion fully hit in. She had been there.)
And now, the other way to look at the Wattses' Greek tragedy. The two heroines, essentially, fight for same.
On one side, there is Shanann, strong, maternal emotionally warm, pregnant, ready to protect her family. She would have never divorced without the fight for Chris, whom she viewed as the greatest father.
On the other side, NK, cold and calculating, but, she, too, wants to be the mother. Her trap is honey-wired, but realistically, CW is a mediocre catch. She, however, considers him as potentially the father to her future kids, because he is so good to his girls.
And between these two women, there stands Chris. Tired of playing roles. He is the greatest father, the nicest coworker, the soft-spoken guy, the rock, the savior. IRL, he has enough of the kids. His love to Shanann has been worn thin by family life, with kids, money, family responsibility, nut allergies, treatments, and lunches. He wants romance and love. Flowers in the prairie signify the freedom to be with his new, exhilarating, childless libertine.
The irony of the situation - CW, in reality, is the horrible father. NK, behind all her free spirit veneer, is merely looking for the bourgeois life, with the wedding dress, a husband, kids and family. Only Shanann is true to herself.
