OK, before I start, I want to let you know that I know it's before 6am and I'm getting ready to write a post on my fridge - I get it, it's not normal. So, now that that is out in the open, I'll begin.
Emily commented a long time ago about organizing her fridge and asking what I do. So. . . here's some pics of my refrigerator (I didn't stage these at all, just snapped):

Remember, I never professed to be perfect.
Yes, I label my fridge. I had a system, but it was just in my head. I got so tired of always moving the food around to the right shelf and no one else seemed to get it. Now, it has labels and food goes where I want it to go. Lovely - it makes me smile. With 3 little ones, I'll take all the order I can get.
My top shelf is labeled "sweet stuff" and "eggs."

Next shelf has a lazy susan - another idea from MeckMom. The yogurt doesn't get lost in the back. We eat a lot of yogurt and it doesn't always fit, but when the lazy susan is empty, I pull from the back. I also keep my sour cream in a squeezy ketchup like thing - see it behind the blueberry yogurt. That has been a good thing in our family. The shelf is labeled "dairy."
Next, is all my leftovers. The bottom shelf is things that don't fit anywhere else.
The top drawer is labeled "meat/cheese/tortillas." The next drawer is "fruit." The bottom drawer is "vegetables." I keep that plastic rug pads (you know, you put it under your rugs to keep from sliding around) at the bottom of each drawer, so I can pull it out and wash it easily.
As for the door:
I need to get milk, I always need to get milk. The top compartment is "butter", then "milk". The first of the shelves is labeled "basic condiments" on one side and "salad dressing" on the other. The very bottom, AKA M's favorite play place, is labeled "condiments" - soy sauce, dijon mustard, etc.

I've had this system for over a year, and it works. I don't have a very large refrigerator, so on days that I Costco shop, it gets stuffed, but for the most part this is what it looks like on a very average day. My kids put the groceries away when we get home from the store and they do a really good job at it. Also, it's easy to look and see what I need quickly - that's what I need in my life. This works for us and thought I'd pass it on.
