So-called mother
Srimad-Bhagavatam
SB Canto 1
He was actually the Personality of Godhead from the very beginning of His appearance. He appeared before His so-called mother as four-armed Viṣṇu.
SB 1.1.20, Purport: Any popular personality with a few traits of mystic powers will display some feat of jugglery and easily become an incarnation of Godhead by popular vote. Lord Śrī Kṛṣṇa was not that type of incarnation. He was actually the Personality of Godhead from the very beginning of His appearance. He appeared before His so-called mother as four-armed Viṣṇu. Then, at the request of the mother, He became like a human child and at once left her for another devotee at Gokula, where He was accepted as the son of Nanda Mahārāja and Yaśodā Mātā. Similarly, Śrī Baladeva, the counterpart of Lord Śrī Kṛṣṇa, was also considered a human child born of another wife of Śrī Vasudeva.
