Toddler Eczema?

Minkyboodle • Baby boy born 💙8/13/2018

I was curious if any of you ladies have dealt with or currently deal with your toddler having eczema flare ups? My son had recently started getting little red rough patches in the crooks of his arms and behind his knees with a patch that will show up elsewhere from time to time— which never seems to bother him. Does this warrant a call to the pediatrician? I’ve never had eczema myself nor has my husband and we are first time parents so I have no idea what to worry about.. Any helpful tips in soothing the rash would also be appreciated —what, if anything has worked for you/your toddler in dealing with this and is this something a pediatrician can diagnose or does it require a dermatologist? Help!
