I have three boys (6, 3.5, and 2) and we are using a non-family babysitter for the first time EVER next week so DH and I can go to my older son's open house. Two 13 year old girls from our neighborhood are going to watch them for an hour or two in the evening after dinner. What should I pay them??? I have never done this before and both girls are just starting out in their babysitting adventures so I am not sure if they have a rate in mind.
