KRISHNA THE SUPREME PERSONALITY OF GODHEAD 1970 VOL 1 CH 7 SALVATION OF TRNAVARTA

"One day, shortly after this ceremony [Krishna's first birthday ceremony], when mother Yasoda was patting her baby on her lap, the baby felt too heavy, and being unable to carry Him, she unwillingly placed Him on the ground. After a while, she became engaged in household affairs. At that time, one of the servants of Kamsa, known as Trnavarta, as instructed by Kamsa, appeared there in the shape of a whirlwind."
