The older son wasn’t with her because she was in the hospital.
The “mothers staying with children 12 months and under” are adult women.
Minor girls with children are being placed together.

Funny thing is I’d read that report on Fox earlier, but had missed that statement. But you can see from the story I linked that it’s not clear, since that story does not differenciate between the mothers who are minors and the other mothers. Although it’s not clear who the statement “Minors with children were placed in the foster care facilities together.” is coming from. Presumbably it’s background information provided to reporters, by either the authorities or by the lawyers for the FLDS and the individual women and children. (The men have no lawyers, at least not ones making statements to the press, since they haven’t been charged with any crimes yet, other than the two charges dealing with “resisting” one or more of the warrant services”.)
