Baby skin matters

I’m no doctor so I can’t tell you what exactly but based on the photo, my son had something similar to this. We switched to Aveeno baby Dermexa wash, it seemed to have calmed his redness down but we were obviously still concerned as it is still significantly bumpy. Brought him to the PD and he diagnosed him with eczema. Prescribed a mild 0.5% steroid cream along with Physiogel AI Lipid Balm (this version is only available at the doctors. Closest version to find in Pharmacy is the cream version). After a few days of treatment, it cleared up completely.
