My friend Judith (Greenburg) who is Reform (very reformed!)has studied a lot of Orthodoxy, and she says she knows of no "ceremony" or "rite of passage" that involves throwing little bags of raisins and almonds.

She said raisins and almonds are symbols of both luxury and fertility which is why they show up in songs, Seder plates and Holiday food. She also said that there are many local customs in Orthodoxy which are not mandated by Talmudic Law. Judith said (in her opinion) it's nothing more than a lullaby with symbolic intent...that perhaps the child (male or female) will be "richer" than the parents.

I have searched nearly every Jewish site I can find, including the Lubovitch site, with no reference found to any rite that involves throwing little bags of raisins and almonds.........

Since the Orthodox are not too likely to show up on the Internet,(although I suppose they could except for Shabbat) this one could be a real challenge for our Conservative/Reform/Comparative Religion scholars. Murray, where were you raised? Were you raised in Ultra Orthodox? I think finding this "rite" may be entirely up to your family memories. Interesting stuff, tho.
