The Luxury Avocado Crib Mattress www.naturalmattressfinder.com/recommends/luxury-organic-crib-mattress-by-avocado/ is a great choice. It may be the case that I made this video prior to discovering that Avocado made a crib mattress. It is a fantastic mattress because it is dual-sided with an infant side and a toddler side. It has all-natural components: natural latex, wool fire barrier, organic cotton and a coconut husk fibre pad that is infused with latex, wool and cotton. It is a good natural crib mattress that you can adapt to your child by flipping it.
I don't go crazy over it. I put my phone on airplane mode at night. I tried a grounding pillow for a while that was connected to a dedicated ground cable, but I ended up getting low voltage shocks from it. Maybe it was picking up voltage from surrounding live cables or from the ground. EMF is not my area of expertise.
