Usual caveat about good and bad nurseries and good and bad childminders.
Personally, I prefer nurseries.
One-to-one is not an advantage of a childminder, unless she had only one baby to look after, in which case I would wonder why she does not have other children to mind? More homely atmosphere at a cm, is probably more accurate. But think of a family with more than one child, baby has to left to cry at some point because the mother/carer is attending to another child - fact of life.
Conversely, I find that in a nursery (which has to keep to the 3:1 ratio by law), the fact that there are more carers means that if a baby is crying, there is greater chance that one of the carers will get to the baby sooner.
I spent hours sitting with the babyroom carers in my ds' nursery as part of the settling in process. So got to observe the goings on warts and all. I would say it is rare to have more than one or two babies crying at once. And if so, help got to that lil'un fairly sharpish. Also, the nursery drafted in more staff to help out at feeding times.
And most importantly for me, for pre-verbal children, the checks and balances that a nursery offered. Less chance a baby will be neglected or worse if there is more than one person in the room at all times.
And yes, lots of sticky messy play. Carers are focused on children, meals are freshly prepared on site by a cook, babies are taken out for walks in buggies (less often now that weather is colder), clean cheery atmosphere.
But you must have a good feeling about the nursery - because there are good and bad. Always visit and ask lots of questions first. Choose wisely.
