ITRANS:

uvāsa katicin māsāngopīnāṁ vinudan śucaḥkṛṣṇa-līlā-kathāṁ gāyanramayām āsa gokulam

Translation:

Uddhava remained there for several months, dispelling the gopīs’ sorrow by chanting the topics of Lord Kṛṣṇa’s pastimes. Thus he brought joy to all the people of Gokula.

The great ācārya Jīva Gosvāmī comments in this regard that Uddhava, during his stay in Vṛndāvana, certainly took special care to enliven Kṛṣṇa’s foster parents, Nanda and Yaśodā.
