There seems to be some sort of "disconnect" (for lack of a better word) between the parents vs. the pre-teen, teen, and adult children. The parents do not have the "fear" of the younger children talking to DHS but I think that comes from their lack of understanding of child developmental milestones for 2 reasons.
1) Developmentally speaking, the very ages that adolescents begin to understand that their parents are just humans with flaws and not idolized as they once were for their "parental awesomeness". These are the ages they start making their own decisions about what they like and how that differs from their parents sometimes. What they think might be different from what they have been taught and the "obey or chose beatings or hell" rigidity in parenting is not really conducive to healthy relationships and has signficant consequences in the longterm. (IMO)
2) The younger children will probably tell more information than the older children about any safety threats in the home through their their play and non-verbal communication. Not to mention their answers to open ended questions, their growth and development, behaviors in a variety of settings - including during parental interaction.
I am really curious about their visits. Is the time spent playing with the children and focusing on enjoying their limited time together? Or is it primarily a congregation gathering for a hell/fire/damnation sermon the entire time? Even if the 30 minute sermon is kept during the visits, are they guilt laden? If they don't have to focus on school or homework during the visits - what do the parents do with the time with the kids? Do the parents know how to play, interact, engage with all ages for fun?
Apparently the visitation has not been given over to worship time--except for the trip home for worship. Prior to the trip home, Hal was saying publically that he was not allowed to pray with the children. Apparently someone clarified for him that prayer is not forbidden.
With that said, I can imagine that supervised visitation--a specified number of hours in some "neutral" location must be incredibly trying for any family. Probably slightly less enjoyable than being stranded at an airport for hours during a layover. I will say that they always manage to arrange a family portrait--and someone in the family (perhaps Michelle) seems to be a very good photographer.
