On the night of the Seder, 5-year-old Miriam was very happy to see that she had her own becher at the Seder.
After Abba made Kiddush, all of the adults at the seder began drinking their cups of wine—the 1st cup of the Arba Kosos. Miriam also raised her cup of grape juice, happy to join everyone else in this mitzva.
“Do I need to drink the whole cup?” she asked herself. “This becher is so big. I don’t feel like drinking so much grape juice. If it was a sparkling grape juice, maybe I would do it. But this one - I don’t like it so much,” thought Miriam as she looked inside the cup that was filled to the brim.
Question: How much grape juice should Miriam drink?
Hints & Answers: LAWS of PESACH: Aruch Hashulchan (ibid.) addresses this question. He writes: ואין צריכין לשתות אלא מעט - “[But children] need to drink only a little bit [from each cup of the Four Cups.]” Based on the Mishna Berura, Rabbi Shimon Eider teaches that a child needs to drink only a cheek-full (i.e., his/her cheek-full) of wine/grape juice. R. Eider adds though, that if a child is not able to drink even that amount, he/she can drink even less than that (Halachos of Pesach, XX C 4).
Note: Menucha’s answer are not to be taken as final decisions in halacha, but rather as a springboard for further study and discussions.
