If you think about it, where does your newborn baby spend most of the time outside of your arms? Sleeping in his/her crib. It only stands to reason that the ingredients in your crib mattress are pretty stinkin important because your baby's breathing them in all the time. With that in mind, I endeavored to find an organic mattress for my baby. We ended up with an organic cotton fill mattress, but O'Baby is giving away an organic mattress--not just the cotton fill-the whole thing!
