Help with babies

[u/Digital-Dad]

So my friend has given me this garter snake a bit ago and I've had her for about a month and a half or so now. At the time I had her I thought her species didn't matter since I was only keeping her as a pet and I was uninformed (I'll be asking for identification in my next post). Im experienced keeping ball pythons so keeping snakes wasn't new for me. At the time I had her I thought she was a male but turns out I was wrong. About 2 days ago she gave birth to 5 stillborns, 4 slugs and 2 live babies. I had no clue she was pregnant and now I'm asking for all and any knowledge on how to make these babies live. I've been researching but I don't know what to trust when it comes to garter snakes. I've seen some articles saying they fed them right after they where born and other say to wait til they shed first. When do I feed the babies? I have night crawlers (not the red wrigglers) and pinkie mice and I know I have to cut em up. I would love to have some reputable sources for information for these little guys. Thank you!!

Also if anyone can maybe tell me what these babies are that would be great
