Thank you for viewing. - Used twice: upon discharge from the hospital and for the two-week checkup. - Home cleaned with baby detergent. - No smokers in the family. - No pets. I was able to use this without any problems for the newborn horizontal hold. Also, because it's made in Japan, there are no seams or metal parts on the areas that touch the child, so I was able to use it with peace of mind.
