L.C.
I never got allowance either - my parents just bought things for me when I wanted them. However, there are a lot of parents that don't do that and feel their kids should work for what they want. My husband thought it was a good idea to teach our son about earning/savings so my son gets allowance. He is 10 and he gets $5 per week for a few chores he is supposed to do. We pretty much buy him whatever he wants so he just saves his allowance and I put it in his bank account. Once in awhile he wants to buy something with his own money so we let him but it is usually something under $20 (and I always secretly pay him back). I think the point is to teach kids responsibility. It also depends on your kids. My son doesn't really feel he needs anything so he doesn't mind saving. He can walk into Toys R Us and not want anything even when we want to buy him something. However, my son has some friends who have to spend whatever is in their pocket just because they have money.
If you don't think it is necessary right now, maybe wait until your kids are older. Hope this helps.
