Help- cello destroyer

I have a beginner 4th grade student who is renting their cello from the company our school works with. He has broken his cello about 2 times since the fall (neck snapped, cracks on the side) and his bridge has fallen down numerous times. Today he came in with a BROKEN bridge. I have had multiple conversations with him, parent, and teachers to avoid this but it keeps happening. He understands he’s carrying/handling the cello improperly, probably too aggressively, but I am not with him enough during the week to know what the exact problem is.

Should I tell him that he needs to choose a smaller instrument (viola perhaps) or to choose another instrument entirely?!?
