I've never seen bees work either of these plants, but I'm sure on occasion they will. It is sold as "specialty" honey in many places and has been for centuries. Not so popular now that Viagra is available...
As far as babies, honey was (and in many places still is) a standard ingredient in baby formula. In recent years they have recommend NOT to use it because it can contain botulism, but so does common household dust, raw vegetables and virtually everything else that isn't sterilized or cooked. I'm not saying you should feed honey to infants, but too pick on honey and not raw vegetables is inconsistent. A lot of this has to do with immunity, but more so a baby''s digestive track is not as acidic as an adult's.
