My child is so spoiled, Who's to be blamed???

Well, in my opinion, it can in many cases be the parents fault. I have 4 children of my own and none of them expect me to buy them things every time I go to the store. But I have a 5-year-old step-son who gets so upset every time I don't bring him something back. His mother is to blame for this. EVERY time she goes out shopping, she gets him a new toy. The child had over 10 pairs of sneakers! No 5-year-old needs over 10 pairs of sneakers. Because they outgrow them in a matter of about 6 months. That many shoes is just a waste of money. But she also buys him the TOP brands and has taught him that having "fancy" things is important. Unfortunately, the boys has no idea what it's like to go without what he wants. I also have a nephew who is quite spoiled by his mother, my sister. She also buys something for her son every single time she goes to the store...and doesn't teach her son the value of money and that it doesn't come easily. The things we want need to be worked for and earned... I was raised that we receive special toys and gifts only a few times a year...on birthday's, Christmas, Easter. My sister and I didn't just receive toys just because. And we weren't spoiled or greedy. It's sad watching my nephew and my step-son when they don't get their way because their mother's have caused this behavior. I truly believe that we do shape who our children will be and as far as being spoiled...it certainly is the fault of the adult in charge of the child.
