You can absolutely get your articles published. Is it a priority for you to only publish articles about pediatrics or are there other articles that you could publish as well? One of my first articles was about ways to have fun with young kids indoors in the wintertime. Just having the perspective of a pediatrician on a parenting topic can be an asset but remember that many of the moms who write articles do well and they are not "credentialed" in any way. For the larger publications, most articles require interviews with "experts" (even if you are one expert, they will want to hear from others as well) and you can find experts through websites like profnet.com. Good luck! Feel free to send a private message and we can discuss more.
