My preemie is 5 months (actual today) and almost 9 weeks corrected. She has been pretty fussy the past few days, drooling a lot, has a little chin rash and sucking on her little fists and fingers constantly. The pediatrician said it is "pre-teething" behavior. When do babies born prematurely start getting their teeth? Do I go by the actual or corrected age for this? Just want to have an idea of what I can be doing to help her if she is in fact teething early!
