DD#1 gets patches of eczema like that, typically where an irritant has been right next to her skin. We keep the area clean and dry plus we use a low dose cortisone crewam, it is the only thing that seems to clear it up. She seems to be outgrowing her skin issues , so hopefully your LOs will be short lived also.
@BoothBaby we've been using the same detergent, soap, and fabric softener sheets since she was born. The only food that we introduced around the time this showed up was apples. I noticed the eczema so I didn't intro anything else for a bit and stopped apples. It didn't go away. And didn't get worse when I gave her more. I'm wondering if it could be from the carpet or the dog hair that gets on the carpet....
