My husband will be the one to relieve our summer sitter. He doesn't always finish work the same time everyday. His job is unpredictable. He could be home at 2:30p or 4:15p. Some Fridays we may need the sitter a bit longer. What's the best way to compensate? The sitter is agreeable to not knowing when my husband will be home. Should we track hours on a daily basis and pay by the hours worked at the end of the week or pay a flat weekly fee?

Re: How to pay sitter?
This is really where I fall. She's committing the time to you. She can't do anything else w/ that time. That's not her fault.
Even if you pay a set amount until 2:30 and then pay extra for when she stays later - I'd probably cushion that extra a little bit to make it feel more worth her while.
