I took my son to his one month check up yesterday. The same day this rash happened. Dr said he just has sensitive skin but I’m worried he could be wrong. To me it looks like an allergic reaction. I breastfeed my son. No formula. The only thing I did different was eat fish(tilapia & salmon) also used a humidifier in the room that night before appointment. He doesn’t seem to be bothered by it.

What can I use to help my baby skin.????
