Despite the desirable convenience and hygienic advantages that come with disposable diapers, safety concerns loom large. Part of the reason parents love disposables so much is because of their no-leak factor. Many disposable brands boast a high capacity for containing fluids, but the bad news is this comes in chemical form -- sodium polyacrylate to be exact. This "super absorbent" gel has been linked to allergic reactions and toxic shock syndrome, and it has the potential to harm your household pets. If that isn't enough chemical exposure, many disposable brands also use perfumes to hide odors and dyes and bleaches to make the diapers look attractive. A study using lab rats showed that the rats had an asthmatic reaction when introduced to diapers right out of the package because of the chemical airborne irritants they were exposed to. These chemicals are extra irritating to newborns, who are still developing and have fragile skin that too easily absorbs all of these toxins. Disposables also have plastic tabs that babies can get a hold of and put in their mouth, risking choking.
