We have a 9-year-old girl, who mostly takes care of herself and requires minimal supervision.
We also have a 14-month-old son, who would need normal toddler care (play time, feeding, bath time, diaper changes, being put down for bed).
Both of our children are very sweet and love to have fun.
Dinner for them would be planned and made ready by us.
Bedtime for the toddler would begin around 7:30/7:45, with bath time, changing for bed, being read a small story, fed nighttime bottle and being put down in the crib.
My daughter can stay up until we return.
Overall, this job should be a very easy going night with two wonderful children.
