This is a new age, money is no longer managed in its tangible form in jars under the bed. Monetary gifts can be given directly into UPromise accounts (not that it'll earn anything, but hey it's the thought right?) Kids are learning to manage and engage everything from a virtual perspective.
So, Yes. As early as the child begins to make purchases with money of their own, whether given by allowance, for special occassion or for odd jobs. Once the child begins to spend money then it is necessary to start undertanding the value and different mediums of money. Several banks offer child credit cards where you control the balance, spending limits, atm withdrawal amounts and have the lexibility to add mney, track charges or even suspend the account. Parents find this invaluable as children grow and mature. Children are able to check their balance, receive statements and the like. Parents can go online at any time and add money or use other controls as needed. All changes are updated instantly. Invaluable when they need an additional 10. while out at the movies or the mall. Check with your bank or nearby banks to see if they offer such accounts for pre-teens or teens. Great opener for teaching about interest in saving as well as interest in charges.
