This is possible, but even taking out the near minimum wage clause I am still surprised that rainier thinks that a 22 year old paid to look after his daughter cares more about her than him and his wife.
You worded that a bit strangely but it's fair to say the daycare worker made a willing career choice that involved taking care of kids all day everyday and is likely to enjoy it a lot and consider him/herself to be fairly skilled at it.
Potentially more so than a tired daddy and mommy, yes.
