Is this eczema???

Eczema or something else? It’s rough and I imagine it’s very itchy, whenever I change him he grabs at his stomach. He actually scratched himself before this picture. He has this on his face too. I use coconut oil on it everyday and cetaphil restoraderm too. Nothing works. It’s been there for so long but it’s never been this bad. (excuse his drool and wet diaper)
