I see your point Argentra. But Iīve seen people advising against climbing elements even for hatchlings with the argument under topic.

And taking your owns words, Iīd say that the same way a grown up bear will not try to climb a tree; a thick bodied BP that grows in an environment with branches will also, as she grows, restraint herself gradually from this adventures and remain more grounded

On the opposite situation, that is if she always lived in a 6"h tube and suddenly is exposed to a branch sheīll explore it and... with no training at all, most likely will fall (and possibly get injured)
