I work in a NICU in a large teaching hospital. In our unit, if a resident ever stuck a kid more than 2x for an LP and didn't call the fellow or attending, their ass would be chewed off. And we wouldn't let that happen.
Also, the baby should have been given a local before the start of that LP...sugar water ain't gonna cut it. and, was there informed consent. We have to have informed and written consent before we do LP's in our unit.
You need to take this up with your manager and the head docs.
And as for the troll Silas....boy, I hope you aren't at our hospital, you sound like a really loveable sort.
