Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 20

Sanskrit:

इत्थं यशोदा तमशेषशेखरंमत्वा सुतं स्‍नेहनिबद्धधीर्नृप ।हस्ते गृहीत्वा सहराममच्युतंनीत्वा स्ववाटं कृतवत्यथोदयम् ॥ २० ॥

ITRANS:

itthaṁ yaśodā tam aśeṣa-śekharaṁmatvā sutaṁ sneha-nibaddha-dhīr nṛpahaste gṛhītvā saha-rāmam acyutaṁnītvā sva-vāṭaṁ kṛtavaty athodayam

Translation:

My dear Mahārāja Parīkṣit, because of intense love and affection, mother Yaśodā, Kṛṣṇa’s mother, considered Kṛṣṇa, who was at the peak of all opulences, to be her own son. Thus she took Kṛṣṇa by the hand, along with Balarāma, and brought Them home, where she performed her duties by fully bathing Them, dressing Them and feeding Them.

Purport:

Kṛṣṇa is always neat, clean and opulent and does not need to be washed, bathed or dressed, yet mother Yaśodā, because of affection, considered Him her ordinary child and did her duties to keep her son brilliant.
