This is one product I would not want to be without when my children have a cold. It helps so much with their cold symptoms (and mine too, because I usually catch what they have!) With menthol and eucalyptus, it really helps unstuff a stuffy nose.
You pour this into the tub like a bubble bath. For a full size bath, they recommend three capfuls, though I've gotten away with a bit less. The vapors rise and noses breath more freely.
You still need to use regular baby soap to clean your children, though. I find that it's a little lacking in cleaning power. But as we only use it when they have colds specifically for the purpose of alleviating their symptoms, that isn't such a big deal for us. It also lasts for a very long time. We're still on the same bottle from when my son was born three years ago.
I would recommend this in any parent's arsenal against children's illnesses. It would make a great gift in a baby shower basket.
