CNAs do work on Mother/Baby and Peds units. I have worked as an RN in the NICU and we did not use a CNA on our unit. We did have one person that worked as an assistant. She helped by bringing supplies, moving incubators, cleaning tools, etc. but she did not perform the usual tasks of a CNA. In the NICU the RN does all the baby cleaning, feeding, bathing, etc. I think working in pediatrics or on a mother/baby unit is a great choice and a very different environment that long term care. You should go for it! Good luck to you!
