A good reference concerning food issues and the adopted child:

"....Lying or Stealing and Hoarding - Lying is a way of saying, "You can't know me. I'm not going to tell you the truth about who I am because if I do, I've let you in. I will live in a world I can control because I'm the one in charge of what's true and false." Children will even lie about crazy things ... like denying they took a whole roll of toilet paper and attempted to flush it down the toilet when the evidence is right there.
Stealing comes from a child's belief that
no one can meet his needs but him. It takes trust and vulnerability to ask for what he wants and needs from his adoptive parents. Instead, an adopted child may simply take it. Stealing can be a behavior that also
satisfies a child's desperate need for control over others.
Hoarding is a related behavior. Having lost their most important connection once, adopted children may respond by hiding stashes of candy, food or other objects they think will keep them safe. Older adopted children may also remember losing all their "stuff" when they were placed in an orphanage or foster home. With those losses in mind, they can obsessively cling to their new possessions like little misers. Hoarding also gives them a feeling of power and control - the bag of candy or box of food they've hidden is something the world can't take away...."

I cannot tell you the number of times our children went to school after eating breakfast and stole someone's lunch on the bus and ate it. Our kids were/are well-built and physically healthy. They dressed nicely and had great manners but no matter how much love and healthy food was given to several of them, it was never enough. I've had children steal Rolaids from teacher's purses, Cokes from the teacher's lounge, birthday cupcakes for another child's birthday out of a teacher's car, and packaged snacks from the student store in middle and high school. I have, in my files, a handmade cardboard sign which says "Want Fuud" which was held up by my 13 year old special needs son in the middle school parking lot. He stood there, sucking his thumb and holding up his sign until someone called us. Thank goodness people knew our family. It was mortifying. See why our children had other activities rather than Halloween or Valentine's Day? It was just far too much for them. As one of our children made his way through school, each and every class had to have their lunches locked up, everyday. If a lunch wasn't locked, it was gone.
It's not about food, most of the time. And it is a totally different issue than a healthy birth child stealing food. Definitely there are children out there who are being starved. We all know that. However, IME, food issues and stealing small personal items go hand in hand with adoption of children past infancy.
I'm very concerned that this child had some attachment issues and that made her even more vulnerable. Children with attachment deficits are often far more physically demonstrative to strangers than their own families. They are also at great risk as they don't recognize danger, will do just about anything for attention or a treat and seem to have a red flag waving which says, "pick me". It's tragic.
I have no idea if this was the case with little Amy. I've just dealt with hundreds and hundreds of children with this same profile. The general public needs to learn about these issues as one out of every 20 people is adopted and many are adopted past infancy.
