>My oldest son, who is 5, enjoyed both seders and he is singing AHAD MI YODEA? the whole day today :)

We like to go around the table for that one, with each person taking responsibility for one number. That is, we all sing "Echad mi yodea"; then, one person sings "Echad ani yodea. Echad eloheinu" and we all join in for the rest. In subsequent verses, the same person sings "echad eloheinu" each time, and with each verse, another person takes on another number.

We also have a lot of fun with Chad Gadya, using a version we picked up years ago that includes sound effects.
