As a fandom we all agree that mo is indeed very little and call him little mo in our heads as well.

He Tian calls him little Mo so it kind of stuck ╮( ̄▽ ̄)╭
Jian Yi usually calls him redhead. Xixi strikes me as someone who doesn’t call Mo that and rather calls him full name - mo guanshan xD I think Mo’s mother calls him little mo but the one who the the audience sees frequently call him little mo with such affection and adoration is He Tian (▰˘◡˘▰)
Also, correct me if I’m wrong, wasn’t it He Tian who let us know Little Mo’s name and the pun behind it: dont close mountain? Hahaha (≧∀≦)
Am I crying
