I ended up getting these silicone ones, and they seem perfect so far. https://www.amazon.com/dp/B07S7YR5M8/ref=cm_sw_r_cp_api_i_R9RyFbR34W9YE

Like any kind of edge cushion, they might not withstand peeling motion, so hopefully your little one doesn’t try scaling them. Fortunately they’re pretty low profile so there isn’t much to bite or grab onto.

Good luck with your little chewer!
