Teach your kids on saving money without giving them more when they want to purchase something that costs more.
When your kid wants to buy a toy that costs $5.
You only have to give your kid $1 per day.
Your kid might want to spend the $1 to buy candy.
You have to let your kid understand that to afford a toy, your kid has to sacrifice the candy to save $1 every day.
On 5th day, your kid got enough savings to buy the toy!
