I've been wondering about this for a while and have been prompted by another thread to ask at what age your children became aware about shopping and money. I've noticed a few people mentioning using money as part of a reward system for children as young as 3 or 4.
my ds1 is 3yr and 3m and has only a very rudimentary understanding of money and shopping. he never asks me to buy him toys or sweets, and I don't think using money as a reward would have much meaning at the moment. We play pretend shopping and he will say things cost 'two pounds' or some such, and he calls coins 'pees' (so I guess he is picking up on 20p etc). Are most kids much more advanced in their understanding than this? Should I be teaching him more about money perhaps by giving him pocket money (though I don't know when we'd find time to go and spend it - wouldn't want it to go on sweets really)?
