Yes! Infants to 5yo will need parents actively participating in the lesson.
6 and 7 year olds will need a parent close by ready to help. However, parent’s shouldn’t help unless asked. Sometimes kids need to work things out for themselves and I’m trained to help them do that.
Most 8 year olds and up do well on their own but it’s still a good idea to have a parent or guardian paying attention so they’ll know how to support the child between lessons.
