I agree that leaving a baby at 6 weeks must be a completely harrowing experience for most moms. I have seen some amazing infant rooms where babies are held and loved all day long, and those rooms have reassured me that quality infant care is out there.
I suppose that many people who are entrusting their infants to a child care situation are doing it because they have to. When parents have to work and family is not available to help, then quality child care is the next best thing.
