I am open 7:30 -5pm. If asked to stay open till say, 6pm, I would charge an extra $8 on top of daily rate. My evening time is very precious to me. 99% chance I would just tell then 'no way' and they can find someone else. But I for some reason, REALLY wanted the family, then I MAY consider taking them till 6pm.
All my kids pay $32 a day regardless of when the come/leave.
I am obviously in Kingston, Ontario.
The norm for my are is $30-$35. There are some SAHMs who will take in a few kids for as low as $20. All the power to them. As Judy put it: "im in it for the money!"
