A lot of is it person-to-person, but for us? We don't give our daughter cash. She has not been shown to be responsible with it. I don't want to buy her booze or drugs or any of that. We do give her toothpaste, conditioner, etc. I keep a good stock of it and will hand it out to her if she needs. I'll also give her groceries that we have from time to time, mostly one-bowl stuff, or mac and cheese - easy stuff. I want her to do as much as she can herself.
