How to clear up this situation? Resentful kids.

I have an adult child at home with a lot of free time and legitimate reasons for not working right now. I also have a late teens child at home, then smaller children as well.Both older kids are wanting extra cash and have a TON of free time. I have also been ill recently. Each morning recently they ask how I’m feeling. If things are rough, they offer to watch the younger kids.I am effusively appreciative and give them as much cash as I can- to the point that we have about the same amount in our account as each of our kids do, lol.Occasionally they act resentful of the setup. I ask them not to offer if it’s not something they want to help me with. But they keep offering for two reasons- to help me through this tough time and also to earn cash.Any thoughts as to how we can clean this whole process up? I’m filled with guilt, they’re resentful, and yet in ways this setup works for all of us. via /r/Parenting https://ift.tt/3xu91pU
