Truth in advertising

I bought some "infant" tylenol(generic version) this week. Right on the box it says for ages 2-3.I look at the dosage chart and it lists under 2, contact a doctor. What I want to know is how in the world do they get away with labeling it infant tylenol when they are marketing it as a toddler drug and trying to cover their butts for a lawsuit by saying contact your doctor.

I am a seasoned parent, i have a chart that shows dosage for infants and so on, so I know how to deal with it. But its still very irritating that they sell a product supposedly for infants that isnt what it says it is.
