One that is a guest in a house with small children and the father was away for Shabbat. The wife made Kiddush for all and then she poured some wine from her cup to small glasses for all the guest to partake. Is a man allowed to drink that wine?

Horav Shlomo Miller’s Shlit’a opinion is that it would have been preferred that the guest should have recited the Kiddush, however, it is permitted for him to drink the wine.
