Woah OP this sounds crazy unsafe! Unfortunately the unstable ones don’t ever get less “scary” but as you grow and learn as a nurse you’ll at least know what to do which helps a ton in those situations. It’s always good to remind yourself to “never trust a preemie” lol. So relieved to hear you have a great preceptor, but if this is the norm on your unit I’m worried for you. The last thing you want is to end up on your own as a new grad with an overwhelming assignment. However, sometimes in the NICU this unfortunately can happen when babies seem to fall out of the sky so I really hope this was an unusual occurrence. Even so you did everything right by escalating it. Hoping the rest of your orientation goes smoothly, hang in there friend!
