When did your baby stand and walk unassisted?

As the title states- when did your kiddos stand up without holding onto something and take steps unassisted? My baby will be 14 months next week and has been pulling to stand and cruising furniture like a pro for a couple months now. In the last couple weeks he will let go furniture and stand independently for 1-3 seconds but that’s it. I know I shouldn’t be worried but I am. He crawls like a pro but he is a very very cautious child and I definitely feel that he’s afraid of letting go for too long.
