Parenting: Communicative Problem Solving - Small Scale Stealing

Parenting requires opening lines of communication and critical thinking, as well as preparing children for the time when they will marry and have children of their own, inshaa Allah. One strategy we use is to present our children with situations and ask them how they will deal with them. This is particularly useful if you have children who have problems with certain misbehavior and want to get them thinking about it from a different perspective. Sometimes you might find that your children suggest a solution you never thought of.

The first in the series of questions, and believe me some of them will be VERY tough, was about small scale stealing.

Parenting Question #1

Ishaaq and Ismaeel are your two sons. Ishaaq keeps stealing cookies, but Ismaeel doesn't. When it is time for a treat, you are planning to give them the cookies, but Ishaaq already stole three of the cookies. What do you do? How many cookies do you give Ishaaq and Ismaeel?

How do you stop Ishaaq from stealing cookies?

If you don't stop Ishaaq from stealing cookie, how do you stop him from teaching Ismaeel to steal cookies?

Extension.
The extension is an additional line of questioning in case the responses are vague or unrealistic, for example, "I will teach them so they don't ever do those things."

You already taught the boys that stealing is wrong/a sin/haraam. They know it is wrong. How are you going to teach them that will stop them doing it anyway? What will you teach them, or do, so they don't steal?
