Lisa -- A number of people have posted about the possiblity of infant botulism
in your "sad baby."    If this seems likely to you and you are trying to
figure out where a six-week-old might have gotten honey, ask whether this
family is Jewish or spent any time over the recent Jewish holidays with
friends or relatives who are.   It is an old and still extrememly widespread
custom to have everyone at the table taste a little honey at Rosh Hashanah for
a "sweet New Year," and if the baby were being held by, say, a grandma who
didn't know that these days we don't give infants honey, he might well have
gotten a finger full to suck.
