What is a Private Day Home?
A day home or sometimes referred to as private babysitting is a private residence that independently provides care for children. The maximum number of children to be cared for in a private babysitting arrangement is six children under 11 years of which three children can be under two years of age. Parents are responsible for screening and monitoring of private caregivers. No subsidy is available in private babysitting situations.
When choosing a private care arrangement parents should be allowed to complete a safety check of the home, this includes viewing all rooms in the prospective home and the outdoor play area.
Parents are encouraged to request both a criminal record check and an Intervention Check for all individuals over the age of 18 years residing in the home they are placing their children. Parents should be able to visit their child unannounced at any time of day. The parent should be permitted to enter the home at drop off and pick-up times
