Toddler Engagement

Families with great toddler nannies ( 1.5yr to 2.5 yr old) - what is your nanny's routine? What activities do they do and for how long? I'm looking for both perspectives, from in home activities and outings as well.

Trying to understand where to place expectations. Is it acceptable for the nanny to sit in one spot and let the toddler roam about unstructured all day while just saying a few words to them every few minutes? This is all I have experienced so wondering if it's standard.
