You will find it is mostly caregivers on this site. A good place to find parents would be through the Early Years Centres around the province.
Based on the first questions that usually come from the parents they first narrow their choices down by price, hours and location usually in that order. Then from their final lists they choose the best of the lot so to speak. They seem less concerned with what goes on in the home and I think in the grand scheme of things they are comparing it to home so as long as they see most of what child is used to at home they are ok with that.
It is also hard when interviewing realizing that generally we are interviewing a family when the baby is only 6-9 months old and the parents themselves haven't really come to grips with what they want for their child when they are 2 or 3 or 4.
