Inclusion Criteria:  Recruitment will be conducted through Calgary Public Health's immunization program. Public Health RNs routinely screen mothers for PPD during infants' vaccination clinic appointments using the Edinburgh Postnatal Depression Scale (EPDS) at 2, 4, and 6 months of age. EPDS scores>12 are indicative of probable major depression with postpartum onset and make a mother eligible for our study. Approximately 500 mothers per year (40/month) screen >12 on the EPDS. The investigators have agreed to support a part-time Calgary Public Health staff person to review screening records and contact potential participants to determine if they are willing to be contacted by a the VID-KIDS Project Manager for further information about the study. If mothers agree, then the VID-KIDS Project Manager will contact the mother to explain the study, further assess eligibility, and if appropriate conduct the informed consent procedure.  Exclusion Criteria:  None as long as they meet Inclusion Criteria
