Eczema help!

Paige

My poor baby(18 months old) has horrible eczema between the crevices of his legs behind his knees. He is always scratching at it like it bothers him 😢 we’ve tried literally every lotion... aveeno...goats milk lotion, dove...another one that starts with a Ex...and nothing seems to help. I’m going to ask his ped maybe for a steroid cream but do any of you mamas have any suggestions?!
