I am serving poached salmon which requires white wine in the recipe for this shabbat (Rosh Chodesh Av). 1) May I eat the leftovers during the week? 2) May I serve it to my children (2 and 3 years old)? 3) May one serve young children their Friday evening meal before Shabbat? Is this considered serving a Shabbos meal, in which case it may be fleishig? Thank you in advance and may the redemption come quickly.
1) Many Poskim contend that in order to encourage the proper celebration of a Seudat Mitzvah, the meat leftovers may be eaten even afterwards (Birkei Yosef 551:6). According to these Poskim, one may eat the fleishig Shabbat leftovers during the following week. However, the prevalent practice is to eat meat only at the Seudat Mitzvah itself (Eliyahu Rabbah 551:26; Mishnah Berurah 551:73) and not to eat the meat leftovers until after the Nine Days (Igrot Moshe, Orach Chayim 4:21:4). 2) In general, it is not permitted to feed children meat during the Nine Days, including erev Shabbat, unless the child is weak (Mishnah Berurah 551:70). The Poskim dispute whether one may feed meat to a child who is not old enough to understand that we are mourning for the Bet Hamikdash. (Dagul Meirevavah and Mishnah Berurah 551:70 rule that one may not, whereas Magen Avraham 551:31 permits.) 3) Rav Moshe Feinstein ruled that if the children are fed their Shabbat evening meal before the rest of the family has accepted Shabbat because it will be too late for them to wait for the Shabbat meal, one may feed them meat at this meal because this is their Shabbat meal (Igrot Moshe, Orach Chayim 4:21:4). However, one may not serve them fleishigs on Friday afternoon if it is not being used as their Shabbat meal.
