CC Madhya 19.205, Translation and Purport

“‘Although Kṛṣṇa is beyond sense perception and is unmanifest to human beings, He takes up the guise of a human being with a material body. Thus mother Yaśodā thought Him to be her son, and she bound Lord Kṛṣṇa with rope to a wooden mortar, as if He were an ordinary child.’

This verse from Śrīmad-Bhāgavatam (SB 10.9.14) is in reference to Lord Kṛṣṇa’s exhibiting Himself like an ordinary child before mother Yaśodā. He was playing like a naughty boy, stealing butter and breaking butter pots. Mother Yaśodā became disturbed and wanted to bind the Lord to a mortar used for pounding spices. In other words, she considered the Supreme Personality of Godhead an ordinary child.
