While this is an important activity for the child, to show ownership of their future and to have some control in their lives, be mindful of the child's emotional well-being and stability. If unsure, do it with a therapist present. Permission and guidance may be needed from the primary worker; check with your agency's guidelines surrounding EcoMaps. Some negative memories could also come out, so make sure caregivers are aware and able to offer extra support.
