Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 5
Sanskrit:
हिन्वतोऽध: शयानस्य मास्यस्य चरणावुदक् । अनोऽपतद् विपर्यस्तं रुदत: प्रपदाहतम् ॥ ५ ॥
ITRANS:
hinvato ’dhaḥ śayānasyamāsyasya caraṇāv udakano ’patad viparyastaṁrudataḥ prapadāhatam
Translation:
Once, when only three months old, little Kṛṣṇa was crying and kicking up His feet as He lay beneath a huge cart. Then the cart fell and turned upside-down simply because it was struck by the tip of His toe.
