lol We are the same way! In fact, we just said last week that we weren't going to get anything else for DS because he has plenty and his bday is in December so he just got done having a ton of gifts. Then today we're in the kitchen and DH says well I think i'm going to stop and grab him one more remote control tractor. I had just come back home from buying him a leap frog scribble and write too. lol
Then we agreed not to buy for each other. I come home and there's like 10 gifts under the tree from DS and DH to me.
