 There's a monster in my pillow. There's one on the rug. The fact is, their next asthma attack could be triggered by something as innocent as a teddy bear or a dripping faucet, even a bath toy. I don't like monsters. Fortunately, there are simple ways you can help prevent their next attack, from putting stuffed animals in the freezer to kill dust mites, to drying bath toys and turning on the bathroom fan to prevent mold.
