Once, His mother tied Him with ropes to a mortar because she had caught Him stealing butter. Then, crawling on His hands, He dragged the mortar between a pair of arjuna trees and pulled them down.
ƒ SB 2.7.27 purport
So at the age of only three months He killed the Shakatäsura, who had remained hidden behind a cart in the house of Yashodämayee. And when He was crawling and was disturbing His mother from doing household affairs, the mother tied Him with a grinding pestle, but the naughty child dragged the pestle up to a pair of very high arjuna trees in the yard of Yashodämayee, and when the pestle was stuck between the pair of trees, they fell down with a horrible sound. When Yashodämayee came to see the happenings, she thought that her child had been saved from the falling trees by the mercy of the Lord, without knowing that the Lord Himself, crawling in her yard, had wreaked the havoc. So that is the way of reciprocation of love affairs between the Lord and His devotees. Yashodämayee wanted to have the Lord as her child, and the Lord played exactly like a child in her lap, but at the same time played the part of the Almighty Lord whenever it was so required. The beauty of such pastimes was that the Lord fulfilled everyone's desire. In the case of felling the gigantic arjuna trees, the Lord's mission was to deliver the two sons of Kuvera, who were condemned to become trees by the curse of Närada, as well as to play like a crawling child in the yard of Yashodä, who took transcendental pleasure in seeing such activities of the Lord in the very yard of her home.
