I must say Yi-ho is a very close to a real baby when it comes to accuracy. Some of yall probably have seen, like me, in other stories (mostly BL/yaoi) where the child's body doesn't look natural--no matter the age. This happens with the Semes too. Some body parts don't match up with the rest of the body, such as hands sizes, neck length, legs lengths, and feet sizes. But Cheong-ho is drawn almost perfectly. I don't think I've seen a Seme in BLs/Yaois where his body is drawn natural and with accuracy, unless I've forgotten or can't think of any.
I think we can all agree that we're gonna miss this story. It's one of the very few where I wouldn't mind if it kept going or have over 300 chapters or whatever like majority of Manhuas.
