I am hiring a nanny for our 2 year old and 4 month old children. She will work mon-fri. The day begins at 8:00am and the end time is variable. The longest we'll ask her to stay will be until 4pm, but if I come home early, then she is free to go. Some days, I'll be home at 1 or 2pm, and in that case she is free to go home. We'll be paying her a weekly salary of $350. Is this reasonable.
