The Court understands institutional or residential care to be placement in an institution rather than with a family, irrespective of the size of the institution and the number of children it can hold. Thus, the terms “institutionalization,” “institutional care” or “residential care” will be used without this constituting an assessment of the way in which this type of care was provided. 553
