HELP- How bad is it to leave job after < 1 year?

[scrubby bubby]

Need opinions on this- how bad is it to leave a job after less than a year working? If you leave on good terms with 2 week notice, does it make you un-rehirable at that institution? I may have to leave my job for unrelated personal issues right now after working less than a year, but I want to work for this same place again once I am ready to work again. Please help with advice- thanks!

Thank you all for your replies, very helpful to have the support and encouragement. My 6-month old is having lung problems, and I want to be home to take care of her, as well as finish my BSN and working is going to be too much. My husband travels all the time for business (gone sometimes M-F out on the west coast) and I really need to be home for my daughter. It just makes it so hard because i've got a year left of school still and don't want to give that up. Plus when I return to work, I am interested in going to a different specialty. I work ICU right now and have been thinking a lot of going to ER or another critical care area. Seeing the NICU nurses care for my daughter several months ago has been amazing, and I am very impressed by what they do. That and the ER nurses have been great. I think it may be my time switch out of the ICU when I am done with my program and I can concentrate on caring for my daughter over the next year. Unfortunately I have only been working ICU for 7 months and i'm afriad it just looks so bad with me leaving so soon. Then, in one year, trying to reapply to the same hospital but a different area. I just hope they understand and aren't upset they spent so much time training me in ICU. I just finished with my preceptorship only 1 month ago, and my preceptor(s) were wonderful. Thanks again for the support.
