Know you area's rules. Not just day care regulation but also school board expectation.

Here, children grade 2 and under must be accompanied at bus stop by adult and met by adult too.

If you day care takes mixed ages, how do they get them to bus or school? If driven, do all children have age appropriate car seat? Is carer insured to transport children who not her own? If she walk to bus stop, how does she transport littles? Are small children out in cold and rain waiting for buses? How far bus stop from home? Does she have waterproof cover for stroller or are littles cold and wet in the wind? Or worse, does she leave littles in house when bus due? Might only be end of her driveway but electrical fire, choking, anything can happen in few minutes. Who supervising children if not all meeting bus? Get police check for them too.

Police check should be shown as well. Two checks to complete. One is for criminal record. One is for vulnerable sector which include crime against children. No point in knowing they never stole a bag of chips if not checking child abuse crimes too.

Screen time - some carer use TV as part of their day. Find out if yours does, how much, etc.

Does carer run errands in business hours? Does she leave children with spouse? You are paying her to care for your child, not her husband or mother. These all question to ask too.
