Best baby wash for babies with eczema?

Randi β€’ In love with my best friend. ❀ 5/26/18 πŸ‘°πŸ€΅ Mama to the perfect baby boy born 11/14/19πŸ‘ΆπŸ’™

We already only use soap on our son once a week and every time we do his eczema flares like crazy, even when we use Eucerin immediately upon getting out of the tub. We use Aveno baby wash. It takes a few days of Eucerin to get his eczema to calm down and then it's time for a bath again. πŸ€¦πŸΌβ€β™€οΈ Does anyone use a wash that's good for eczema that they like? TIA!
