PURPORT

When Krsna 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 Krsna and Balarama and exclaim, "Oh, see how Krsna and Balarama are crawling!" Upon hearing this, Krsna and Balarama could understand that these were not Their mothers They were following, and They would return to Their actual mothers. Thus the crawling of Krsna and Balarama was enjoyed by the people of the neighborhood, as well as by Mother Yasoda and Rohini and the two children Themselves.
