Query: Beware of FLAME RETARDANT CHEMICALS!

Nowhere in the item description does it mention that this rug has been treated with flame retardant chemicals. But it comes with a sticker on the back that clearly states that is has flame retardant. This is absolutely absurd. Both wool and leather (the only two "components" of this pelt rug) are naturally flame resistant. There is evidence flame retardants may be dangerous and harmful, especially to infants.[...]Why then is this advertised as a baby sleeping rug with no mention of the flame retardant chemicals used? We bought this as a sleeping pad for our 4 month old daughter, but unfortunately she will not be able to use it due to the potentially hazardous chemicals that were not mentioned in the product description.
