My friend gave her typical son a weekly allowance and made him split it 3 ways: Save, charity, and spend. Spend bag (they were literally 3 ziplock bags that she kept) he could use right away on whatever he wanted, but she basically did this so that when they were in the toy store, he had to make the trade off between what he had in his account or a toy he really wanted that he was saving for. When he asked for a toy, she would remind him that he could buy it but would have to use his own account. Also, I recall she did not split the money equally among the three bags, each got a different %. Maybe charity was like 10%. That way, he didn't have to wait forever before he could afford a toy.

Is there any possibility that the issue could be different than not understanding? One of my kids (when he was your son's age) once had a thing where he wanted us to take him to McDonald's everyday. I'm not sure if he didn't understand that we couldn't go to McDonald's everyday or if he thought he was persistent enough he'd get what he wanted. We would tell him we weren't going to McDonald's that day. He'd get mad. He'd keep asking for it. It took months for him to stop but he did stop making those same requests over and over.

If the tablet is the source of the ideas, maybe you could take the tablet away? I'm guessing he wouldn't take that well but it might be worth it in the long run.

Thank you - we were considering this for him but not sure he understands the concept of money. He has piggy bank with a lot of coins and some dollar bills, he thinks he can buy the whole toy store with it :) With my typical daughter she does some jobs at home from time to time that her father just makes up and she earns some money this way. it's easier with her because she simply understands :)

It could be the repetition of doing the same thing everyday with gratification for liked food is a big motivator.

i would try telling him he can earn one of the things he sees, but only one. He can earn money for little things, like picking up his clothes and putting them in the laundry, brushing his teeth when asked, helping mommy empty the dishwasher. etc..he may not understand money, but he can learn earning things. Like daddy going to work to earn money for things we want and need. We had an ABA therapist for 2 years, they were very helpful. you might consider getting some help.
