Al-Miqdad (May Allah be pleased with him) reported in a long Hadith

We used to reserve for the Prophet (ﷺ) his share of the milk, and he would come at night and offer greetings in such a manner as did not disturb those asleep and was heard only by those who were awake. In fact, the Prophet (ﷺ) came and offered greetings as usual.
