I think your plants should be safe for your little guy! I did read in another thread that Yucca leaves might be hard to grab on bc the leaves are very wide (for babies).
I would put something sturdy running through or near the leaves of the yucca since their leaves don’t offer a lot of support (but that doesn’t keep mine from hanging out on hers lol) and if you look to add any more plants in the future I would 100% recommend pothos! My baby loves to nibble on her and I find her hanging out in there more often than not — she loves it! That’s a beautiful palm by the way!
