I found that most day cares will tell you what you need to know. I would specifically ask about staff turnover. One of the things I really like about our day care is that they have low turnover and we have had consistency in our care givers. For infants, I would ask about feeding and sleeping schedules - do they follow a specific schedule or do they follow the infant's (most follow the infants but something to ask about). I was planning on breastfeeding so I asked about sending breast milk - I wish I would have asked more specifically about their experience with breast fed babies. We had a few issues but were able to work things out. Good luck!
