grouphug IMO (which is how I presented it - I actually said "those of us who feel uneasy with...."
the difference IMO is partly in extent (ten hours a day from the age of two weeks for example) and partly in nature of the childcare - IMO employing a nanny who does so many of the intimate and personal aspects of the child's care that she is in effect more of a parent to the child than the parent is. Nannies who do all of the child's washing/meal planning/playdates/remembering stuff for school/organising activities, while the parent sees the child for an hour or so around work.
I didn't single out mothers, and I didn't forbid anyone else their choices - I said I feel uneasy with it.
