Pocket Money.
A number of people believe that pocket money teaches teenagers to be responsible. Others say that teenagers are too young to deal with money and that their parents should just buy them what they need.
Many parents wonder whether to give pocket money to their children and how much to give. Most Moms and Dads think that pocket money helps the child learn to handle money sensibly. However, pocket money may become a battleground if not handled correctly from the very start.
Personally, I think that by giving pocket money parents help children learn to manage money while they are young. It also helps them make choices and feel that they are important members of the family. Even a small amount can give a child the feeling of responsibility and independence. Parents can suggest the child keeping a little book in their money box to record ins and outs. This will help with their mathematics and will encourage them to save money.
But in some families children are given what they ask for and do not get pocket money. Some parents think that pocket money can cause a number of problems. For example, if children have a lot less than their friends they may feel depressed and may be tempted to steal. On the other hand, when they have much more it can cause envy and resentment amongst their friends. Besides, I believe that parents should never give pocket money to their children as compensation for not spending enough time with them and as a reward for helping around the house.
To conclude, I think it is up to parents to decide whether to give children pocket money or not. Anyway, parents should explain their sons and daughters that lots of money cannot buy love and happiness.
