Yeah, I was about to mention... all tort plastrons are soft when they're born. It's from the yolk sac and it does take a while to harden up. Often more than one month. My then-hatchling redfoot's plastron took maybe 3-6 months to fully harden.
So, point being: Don't worry so much!
Also, for future thoughts, as soon as your vet said he was unfamiliar with handling hatchlings I would not have allowed him to perform any treatment. He should've told you all tortoise hatchling plastrons were soft; that's common knowledge.
