I think that it is jurisdictional. The first kid is in Missouri (Kansas City) and she had the second, and now lives in, Kansas. She had problems in Kansas as well, but they acted more reasonably:
Citing Mindi's pending case over Q.A.H., Kansas authorities took Jace at birth and placed him in foster care. But they soon returned him after finding no evidence that Mindi posed any risk to her son. As a family therapist testified, Mindi has provided a "nurturing, loving environment and had met all of [Jace's] needs."
It doesn't seem like Missouri really ever gave her a second chance.
