I agree with SUzanne (which I always seem to do!
In addition, it seems unprofessional to get two months Labour training from an institution and then just leave. Many places now have their nurses sign an agreement to stay for a period of time after getting this training.
As a traveler, you are essentially stepping in and saying you can handle MANY, if not all, situations possible within your specialty. Training over two months will not expose you to that many situations. See, your preceptor will try to get you to experience as many difficult births as possible, but depending on where you work, etc, there may not be certain things seen in 2 months. If you are working 36 hours this is only 24 shifts.
I oriented in the ED, over 6 weeks, and for the first year, I was constantly encountering new stuff that we had not seen during orientation. At those points, I needed some help from the Charge Nurse, the Attending doc, or another nurse. I had resources. As a travel nurse, occasionally the "team" doesn't want to help out the traveler and this puts the patient in danger. Orientation is only the beginning in a specialty.
I know this seems discouraging, and I have read your other posts, you seem like you really want to travel, but to have a good, successful travel career, it is really so so important to have a few years of practice under your belt.
