Not sure. I didn't get the impression it was too long before WT went missing. Do you remember how the first pic released had a little bruise on his face and she jumped into the FB conversation insinuating it meant he was abused but she set the story straight saying it was because of something that happened at preschool? She was definitely still up-to-date with WT and his life (same goes for his sister).
I've always had the feeling - and its just MOO - that KT had nothing to do with those kids being in care, nothing to do with his disappearance, and her apparent lack of 'care' is a combination of her own relative youth, having a new and intact family to care for, having not had custody for a quite long time, and some limitations based on FACS rules or other reasons. Plus we don't know what she says in private even though she puts a lot out there publicly.
