I know that when you take the side off of a crib and sidecar it, you need to shove something on the other side of the mattress to close the gap.
My question is, what does one use?
I've heard of craft foam, and I can see where that would work. But I'm going get a natural mattress specifically because I don't want that kind of foam in the mattress, so why would I then stick more in the crib?
What would be a good and also natural alternative?
