Early Childhood Playgroup

Play is an essential part of socialization. Children make friends as they play together. Having appropriate play skills is vital, so the group provides direct opportunities for children (age from 1.5 to 4 years) to learn play skills. Children on the spectrum used to play by themselves and ignore others. Dr. Sin has excellent abilities to lead disengaged children to participate in activities with other children with their parents' involvement. Dr. Sin led several early childhood playgroups at  SPIN and received a lot of positive feedback from parents.
