I would prefer nanny until 15 months, and then daycare after that. So I guess my answer is cheating because I prefer them at different stages.

The logistics of dealing with paying a nanny is a big headache so that's a big reason to prefer daycare. But childcare has generally been more reliable with a nanny (not calling in sick) than charlie getting sick and staying home from daycare with no backup childcare.

What about you..... if money were no object, which would you prefer?
