I have a couple of ideas for you but I first just have to say I've never been able to be as organized as it sounds like you are. In my younger years I wanted to be organized. Now that I'm older, I'm retired and my daughter is grown I've discovered that there are so many more things that I'd like to do instead of keeping an "organized" house. I am determined to experience the life with my grandchildren that I missed when raising my daughter. Watching a special movie with my grandchildren is a whole lot more satisfying than even cleaning out my refrigerator.
Here are some organizing ideas. What kind of containers are they in? If they're sturdy like a jar or refrigerator box you might be able to put a sturdy strip of cardboard in between each
category ie: between fruits, meats, veggies.
Another idea is to either use small boxes with low sides or purchase organizing boxes and have a box for each category. With low sides you can more easily see what is in each box/tray. You can even take the box/tray out to look inside or to put more inside.
Are you making your own baby food which has to be refrigerated? Or putting the commercial jars and boxes in the refrigerator? If the food is sealed you can keep it in the cupboard, again using a small low sided box and tray to keep them organized.
I did enjoy keeping house and a certain amount of order and I've gone to far in the other direction now so I'm working on finding a middle ground. In the meantime I feel especially blessed when I spend time with my grandchildren.
