Srimad Bhagavatam Canto 10, Chapter 08, Text 36

SB 10.8.36

yady evam tarhi vyadehi-
ty uktah sa bhagavan harih
vyadattavyahataisvaryah
krida-manuja-balakah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Mother Yasoda challenged Krsna, “If You have not eaten earth, then open Your mouth wide.” When challenged by His mother in this way, Krsna, the son of Nanda Maharaja and Yasoda, to exhibit pastimes like a human child, opened His mouth. Although the Supreme Personality of Godhead, Krsna, who is full of all opulences, did not disturb His mother’s parental affection, His opulence was automatically displayed, for Krsna’s opulence is never lost at any stage, but is manifest at the proper time.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Without disturbing the ecstasy of His mother’s affection, Krsna opened His mouth and displayed His own natural opulences. When a person is given varieties of food, there may be a hundred and one varieties, but if one likes ordinary saka, spinach, he prefers to eat that. Similarly, although Krsna was full of opulences, now, by the order of mother Yasoda, He opened wide His mouth like a human child and did not neglect the transcendental humor of maternal affection.
