How much cash for incidentals?

<p>I gave my kids a little less than $200/month while they were in college. That was plenty, but since I required them to account for it, they both chose to have 5-10 hours/week jobs so they had money I couldn’t ask them about. </p>

<p>That said, I was stunned by how much LESS they spent on some things (and how much more careful they were) once they graduated and it was their money they were spending instead of ours. If I did it again, I might give them less money and ask them to justify additional amounts instead of giving them the money up front.</p>
