If the reason you need to know is to figure out how to wash it, you could simply plan to hand wash it to be on the safe side. Baby things are small and usually don't take forever to wash or dry.
If there are other concerns (such as potential allergy), the smell and feel tests should give you a clue. You can also ask other knitters to smell and feel it if you're not sure you know how to tell. Alternatively -- neither of the "destructive" tests requires more than, say, half an inch of yarn or a pea-sized quantity of fuzz. Carefully clipping off some "fuzz" from the inside without actually cutting any yarn, or looking for a place to clip a little off the inside of a seam allowance, could let you be sure.
