“When Krishna and Balarama were crawling about Vrajabhumi, They were enchanted by the sound of ankle bells. Thus They sometimes followed other people, who would enjoy the crawling of Krishna and Balarama and exclaim, "Oh, see how Krishna and Balarama are crawling!" Upon hearing this, Krishna and Balarama could understand that these were not Their mothers They were following, and They would return to Their actual mothers.” (Shrila Prabhupada, Shrimad Bhagavatam, 10.8.22 Purport)
