Looking for a gentle eczema lotion

Shelly • Mama to 👦🏼 Jesse 6/4/19 & 👶🏻 Jameson 3/11/22

So, Jameson just had his first ear infection & was prescribed amoxicillin. Turns out he’s allergic to amoxicillin & broke out into full body hives. He’s doing better & the hives seem to be going away but it’s also seemed to exacerbate his small eczema patches. We’ve been using Zyrtec but have stopped since the hives are doing better & he’s also been getting oatmeal baths. We typically use Eucerin eczema lotion but I don’t know if it’s doing enough? Any recommendations?
