If Lord Krishna was the cousin of Pandavas, then why did he not meet them in childhood?

If Lord Krishna was the cousin of Pandavas, then why did he not meet them in childhood? As per Mahabharat text, Shri Krishna meets Pandavas only during Swayamvar. It is recorded in the Swayamvar Parva, where all the kings are assembled to win the hands of Krishnā (Draupadi). The Pandavas enter the avenue disguised as Brahmanas. Here is where Krishna speaks to Balarama about the Pandavas. On seeing the five Pandavas, like elephants in rut that had come to a lake full of lotuses, like a fire covered with ashes, the chief of Yadus began to wonder. He told Rama (Balaram), “That is Yudhisthira. That is Bhima and that is Jishnu and those are the valorous twins.” Glancing at them leisurely, Rama cast a pleased glance at Janardana. Chapter 178 - Swayamvar Parva Since Krishna is able to recognise all the five brothers, they might have met them during childhood. However, the instance is not recorded or perhaps left for the readers to articulate using their intelligence. Another instance, which proves that Krishna could recognise his cousins is also in the Swayamvar Parva. Post winning the hand of Draupadi, Bheem and Arjun are attacked by the Kshatriyas who are angered of losing to a Brahmana. As both the brothers are showcasing their valour, Krishna once again relates the following to Balarama: On seeing the unthinkable feats of Jishnu and his brother, Damodar, the one with superhuman intelligence, turned to his brother Halayudha, himself the performer of awesome deeds and said, “ O Sankarshana! The warrior who has the gait of a mad bull and who holds a great bow that is 4 cubits long in his hand must be Arjuna. If I am Vasudeva's son, there can be no doubt about this. The warrior who has uprooted a tree with this strength and is instantly ready to recluse the kings is undoubtedly Vrikodara. No other mortal on earth can perform such a feat today. O Achyuta! The other one who left a while ago, with eyes like lotus petals, slender and with the gait of a powerful lion, humble, fair and with a long and shinning nose, must have been Dharmaraja. I am sure that the other two youths, each like Kartikeya, must have been sons of the two Ashvins. I had heard that Pandu's sons and Pritha had escaped from the fire in the house of lac. Chapter 180 - Swayamvar Parva Also, Vasudev and Balaram reach the place where Pandavas and Kunti have hid themselves. Seeing Krishna, Ajatashatru, chief among the Kurus, asked hum about his welfare and said, “O Vasudeva! When we are living here in disguise, how did you manage to track us down?”. Vasudeva smoked and replied, “O king! Even when fire is covered, it comes out. Who but the Pandavas can display such valour among men?” O destroyers of enemies! It was through good fortune that you escaped from that fire. It was through good fortune that Dhritarashtra's evil son and his advisers did not succeed in their desires. Chapter 183 - Swayamvar Parva Although Mahabharat does only mentions the first instance of Krishna seeing the Pandavas and recognising them, there is no records if they had met in childhood. However, knowing that Krishna could perfectly recognise the Pandavas and also they could recognise Vasudeva, the readers that use their conviction to understand they might have met during childhood and hence could recognise them
