SB 10.11.12, Translation and Purport

Once, after the uprooting of the yamala-arjuna trees, Rohiṇīdevī went to call Rāma and Kṛṣṇa, who had both gone to the riverside and were playing with the other boys with deep attention.

Mother Yaśodā was more attached to Kṛṣṇa and Balarāma than Rohiṇīdevī was, although Rohiṇīdevī was the mother of Balarāma. Mother Yaśodā sent Rohiṇīdevī to call Rāma and Kṛṣṇa from Their play, since it was the right time for lunch. Therefore Rohiṇīdevī went to call Them, breaking Their engagement in play.
