Not always true, but it helps. :)
Children's is super hard to get in, but you can always try. They will want to look at your CNA experience, where you did your clinical (hospital peds helps), how you did in nursing school, volunteer experience (again, any experience working with kids helps). Good luck. It may take you 6-9 months to find a job as a new grad in Denver, but some people are lucky and maybe you are one of the lucky ones.
