Why is this so hard?

I have been thinking about redoing Bears room now for awhile. Classic Winnie the Pooh is adorable for a baby, but not for a toddler who is obsessed with cars and trucks. So yesterday at Walmart, I bought him a new crib sheet with cars and trucks and Cars pillowcase and a Cars blanket with every intention of making this happen. Today I went into arrange everything for photos because I want to sell the Pooh stuff on craigslist or Ebay. I started pulling things down off the wall, and I got the bumper and quilt out and I felt tears welling up inside me. I got the pics taken and now I can't download them. I mean I can, I just can't bring myself to do it. This is my babies stuff! I don't want some stranger to have it in their house! I know it is totally ridiculous to do a screening for baby bedding, but I want a background check done of anyone who thinks about buying it. Am I just being emotional? I am all about out with the old and in with the new. Why is this so hard? I know that I could keep this stuff till he was 5 and still have a hard time getting rid of it. So I will probably pack it all away and store it until he has children of his own. And him and his wife(who I will have screened) will look at me like I am nuts and I will tell her, "Just you wait..."
