I read the other responses about allowances. That would be my suggestion, too. If we only looked at this 7 year old, it might be easy to say "You can come up with $7 a week," but then if you don't give to your others, you might caus them to steal in order to cause you to give them an allowance. I read somewhere that half their age is a good place to start, and they can earn extra with chores at the parent's discretion. I have an 8 year old who can earn $4 a week. She doesn't always earn it because of not doing chores. I have a 3 year old who gets $1.50 and a 5 year old who gets $2.50. It's a good way of teaching saving, tithing, and also they see the value of money a little more (still not perfectly). Your son could have to earn his allowance for several weeks to pay back the amount taken from you. If you set up an allowance for him, I'd suggest an allowance for the others (except the baby of course)...just so you avoid hurt feelings. Hope this helps.
