I bet that Nerdanel kept the house baby proofed even once all her kids were adults because She Just Knows Them That Well. All the tables have rubber corners because Celegorm probably responds to everything with “Fight Me” (and he does, in fact, fight them). There is a stair gate in front of almost every room because despite being The Sons Of Feanor only 3 of them have figured out how to open it.

She’s not overprotective, she just doesn’t underestimate them.
