Yes, cedar moth ball things and also some kind of cedar sheets lining it. I'm not sure if they add extra cedar oil to those things or if they are just plain cedar, but once we opened the box the smell was strong. It was pretty close to the back of the rack...not touching it but a few inches away. I just assumed it was a box of clothes (what it was labeled as) and never opened it. We have fans in the room, and I guess the way they were circulating the air, it was moving air past the box and into the tubs of the babies we lost.
If I had opened the box and known, I wouldn't have put it there, but it was one of those things...trying to clean out my grandparents' house, we were all kinda just dealing with a lot and just trying to get it over with.
Just figured it might be useful info to someone...I had always known cedar was bad, but figured it irritated the respiratory system. I had no idea it could cause organ damage.
