Some are born with Natural knowledge, but most of us have learned from mistakes
Sixteen years ago, I let my infant sleep on a plastic mattress filled with foam rubber. I had read the baby books and collaborated with pregnant friends.
But nothing and no one pointed out that standard mattresses contain petrochemicals or that these chemicals off-gas for us to breathe and absorb. Even when the baby developed sleep apnea -- and had to sleep wearing a halter monitor and alarm because of a family history of crib death -- I did not question the standard crib mattress I had purchased from my local baby supply store.
Truthfully, if someone had told me to raise this question, I probably would have laughed and, privately, considered that person to be a little crazy. Everyone in the United States buys and sleeps on traditional mattresses every day. If there were something wrong with that, we would all know, right?
