Random rash 😞

Rachel

Hey mamas! Looking to see if anyone has dealt with a rash like this. He's been getting random dry, red, raised blotches on his body for like 5 or 6 weeks now. Typically I'll just rub him down with a ton of Aveno before bed and by morning they're gone. However today they are all over his back, the back of his legs, arms and his cheeks are both very red and dry, almost scaly? I can't figure out what it is and what's causing it? No new foods were tried today, no changes in detergent or clothing, no change in shampoos or lotions. Could it be eczema? Luckily it doesn't seem to be bothering him but I'm nervous if it keeps reappearing and spreading it's going to start bothering him.
