Rash on lower half of toddlers face

LO is 15 months and has eczema. Well for the past couple of days she’s gotten a rash on the lower part of mouth. It’s small red bumps around her mouth and cheeks. I don’t know if this is a good allergy, but I haven’t really introduced her to anything new and I stopped feeding her any other suspected foods and it’s still there.

I’m starting to wonder if maybe it’s just dry skin and an eczema flare up? The skin does look dry and she’s been having other flare ups on the body. I also wash her face especially the mouth a lot- just water. Because obviously she makes a huge mess while eating.

Only other thing is maybe she’s allergic to the cats? We have 2 cats she loves to rub against so maybe allergies to the cats? I don’t know, doctors office won’t be seeing her this week.
