I don't like the wording in the KC Star where CS says that she is laying down ground rules for questioning "in exchange" for the longer interviews that LE wants to do with the parents. Like this thing is a giant swap meet to barter at instead of an active investigation for a missing child. I know it's probably just poor word choice on the part of the reporter, but the parents and their team could be spending less time discussing questioning and just get it over with.
Also, I have worked as an RN for several years in all areas of maternal/child health- NICU, Labor & Delivery, Postpartum, Nursery, and Antepartum. You would not believe some of the situations I have seen newborns go home with the mother into, despite a CPS consultation. People who were most likely psychotic. As long as they know how to answer the questions correctly, everything's fine. And a lot of these parents have been around the block with the CPS system and know what to expect and what CPS expects.
Conversely I have seen relatively benign scenarios, where CPS/Social Work was triggered as an automatic referral (things like a positive urine drug screen on admission, no prenatal care, what have you) and just from mom or dad being uncooperative, I have seen the baby removed from the home. The absolute worst thing the parents can do is become defensive and uncooperative. Even if they think it's silly, a waste of time, or offensive, if they cooperate with the care plan, everything will be peachy.
That's a bunch of unneeded information probably, but just my past experience to say that I think DB/JI have a long way to go before having their boys removed, or even getting an open case with CPS.
