The reason I highlighted that statement of Barbara's is because I found it very profound and most likely accurate for a young child to make this association.
For example, I have tried disciplining her in "time outs" in her room, that did not work. When I tried the technique of taking away something she loved (i.e., her bunny, CD player, certain video's, favorite clothes, etc.), she would correct herself so that she wouldn't lose the item she loved. She loves the item so much that she was willing to change her behavior to keep it.
So in her young mind, she jumped to the conclusion that she wasn't loved/wanted and that is why she was given away. A very inaccurate statement, which was explained to her. She doesn't know what "take care of you in the way she wants you to be taken care of", means yet. She will ask when she is ready, but for now, I answered her question, assured it wasn't so, and she moved on. I didn't keep her on the subject, I let her take the lead. I'm letting her process this at her pace.
It's kind of funny in a sense that the agency told us to tell her "her story" often when we bring her home and we have, however I realized today, she never really got any of it, until SHE starts asking the questions.
