Everyone earns their own money and has to do decide how to spend it. I don't consider WDW a "gift". For us, WDW is one of our yearly trips (the other trip varies), although not necessarily every 12 months. We went Sept. 2004, May 2005 and are planning Dec 2006. Every year, but not every 12 months. That can greatly affect what I'm willing to spend money on.
I wouldn't buy clothes in May because everything from September still fit. I also don't buy "junk" souveniers. I don't buy anything he can get at home at
Walmart--for less money at that. It also has to say
somewhere "Disney" on it. These, of course, are our rules when buying anything. Without fail, DS4 picks out one of the big foam dinosaurs in AK as a HUGE dinosaur fan. He does also like to get a magnet, but it gets well used. Since we do pressed pennies, we don't hear a lot of the "I want"'s.
It is a little hard on my DH to do this. As a kid, when they were lucky enough to go anywhere, do anything, they were only given admission. A ticket into Six Flags, but
NO souveniers. Even snacks had to come out of their own pockets. His childhood money situation has greatly impacted how he views things and wants to do things for his own kids. It's not that he didn't turn out fine (although his brothers and cousins are all questionable

), but he doesn't want his children to feel the way he did. And because of this, at times, we can be over indulgent (I came from a wealthy family so I'm used to being over indulged as a child myself). But hey,
I figure it isn't the child who gets a lot/has a lot that is spoiled. But the child who doesn't know the word "no" or appreciate what he/she has.
