When His father Vasudev took the Lord from Mathura to Gokul and left Him there in the middle of the night at Nanda Maharam house, The Lord was feeling thirsty and there he was fed by Mother Cow for the First time.
However, it's worth noting that the Lord loves the cows unconditionally, it's an eternal matter.
Yes, Amlesh prabhu.
The Lord's pastimes are going on eternally in Goloka...
Please bless me that even if I don't get to join Him there, I will never forget Him in my future births.
