JMO – To me this began as a wonderful idea to FFC and MFC in deciding to become involved in fostering after their focus on trying to have a child/children of their own. They would no doubt, as with others who have also had much difficulty, had to bear disappointment along the way, so their anticipation in being handed a boy and a girl siblings would have created excitement for them (MOO).
At around 47 years of age when they were handed a baby boy of approx 7 months in age, and his sister who was aged approx 2 yrs, this would be a demanding role for both foster parents, and they obviously survived this until William was approx 3 and a half yrs old (when he disappeared from their care after an overnight visit to the FFGM).
However, these fostering roles may have turned out to be fraught with difficulties that they had not anticipated (continual difficulties for the FFC associated with Bio Parents visitation rights). In trying to control the difficulties being experienced in that state of affairs, especially as William grew to be older, FFC became frustrated and desperate to end her stress. Her stress being ended did not occur …. by diverting the focus onto an abduction theory, she was able to relieve it for a while but, of course, it was bound to surface again. This is just MOO on this sad case, but hopefully LE can solve what happened to William.
