Sorry but I must add another question. Is there not a problem drinking wine for Havdala on Sunday night, since as we know some mourning traditions still apply on the morning of Monday?
A. In principle, although we know that the some Nine Days’ restrictions continue until at least midday (Chatzos) of Monday the Tenth of Av. However, Mishnah Berurah and Aruch Hashulchan disagree if on the Sunday night Havdalah– after Tisha B’Av one may drink wine for Havdalah.
Mishnah Berurah concludes that Motza’ei Tisha B’Av is not as restrictive as the rest of the Nine Days, and one may therefore personally drink from the Havdalah wine without necessitating and finding a child to drink.
Accordingly, the bracha of ‘Borei Pri Hagafen’ would be the bracha of choice on the Kos for this Sunday night Havdalah.
Yet, the Aruch Hashulchan disagrees, maintaining that the Nine Days restrictions are still fully in effect until the following day, and it is therefore preferable to make Havdalah on ‘Shaar Mashkin’ (Chamar Medina) and not wine.
A third opinion, that of the Elyah Rabba and Pri Megadim, is that one may use wine, but should give it to a child to drink, similar to the Rema’s ruling on a standard Motza’ei Shabbos Chazon, due to the ‘Nine Days’ restrictions.
