Children and families do not need any skill or prior art experience and the art studio is a safe place where children can gain a sense of independence, greater emotional regulation, and confidence through self-exploration. Expressive interventions in art therapy can treat behavioural issues, anxiety, depression, ADHD, autism, learning disabilities, physical and developmental disabilities, and attachment difficulties. As a parent of three young children herself, Tammy understands the complexities of family life using compassion to help parents feel more confident in their role of raising a successful family.
