Salsa, of I'm sitting for a longer period of time, I will usually charge $15 per hour, especially if it's during the day and I'm with the child/ren a lot. If it's a shorter amount of time during the day I charge $20. For things like putting the kids to bed/minding them and the house at night, $15. I'm sure a lot of people would also be happy to work out a daily pay rate if you needed someone for 8 hours, but I think that would work best if it were a more regular arrangement, iykwim?
