If you do not like the advice coming from someone who has been in your chosen field for many years, then so be it. But do not get offended when you put out a question online and you do not get what you want to hear. My post was simply concerning time. 12 hour shifts, which is what most RNs work, take their toll. Your background is honestly of little importance on that matter. If you doubt me, look at the tons of evidence based research on how nursing schedules affect the lives of nurses.

Mine, and I am sure everyone else's concern here really is not so much for you as for the animals. I think starting with 4 is a great idea, vs the 16 or so you listed before.

Just do not be surprised at responses you get from people who do not know you personally when you ask them for input.
