Honestly, you would have to ask the child to explain what their drawing means to them. Each individual attributes different meanings to things. Even the colour the child choses to use can have a symbolic meaning. What that specific child associates that object, shape, or colour with can only truly be understood when the child shares that information. Establishing trust is essential for interacting with traumatized children. When they don't trust an individual they are around, they are skeptical and more closed off. This behavior says more about the practitioner than the traumatized child. When the practitioner comes off as controlling or forceful (s)he loses the ability to interact with that child.
