Additional Study Information: The purpose of this current study is to investigate the efficacy of a group model of Family Nurture Intervention in ameliorating behavioral problems in preschool-aged children. The behavioral, neurobiological and clinical insights gained from this project may eventually lead to better treatment of emotional, behavioral and developmental disorders. The investigator hypothesizes that the children who are treated with Family Nurture Intervention (FNI), which incorporates interactive touch with vocal soothing, and family practice in comforting, will show increased emotional connection and mother child co-regulation with better results in the outcome measures in the short term and long term.
