The average daycare gets $7-10 per hour, by my calculations anyway. So go a little under that. How far do you have to drive with gas sky high? How hard is it to get out with all three kids? What is her financial situation? Talk to her about it. Maybe agree to a trial period with a trial price. Giving you the option to raise the price if you feel you are doing more work than expected. Just remember to be honest with her. I would rather have a good friend than extra money, but I wouldn't want to feel like I was being used either. I hope I didn't just complicate it for you. Good Luck.
