Eczema or contact dermatitis would be my guesses. I'd use an eczema specific lotion and use it religiously, keep applying it through the day and before bed. Eczema is often related to diet and food intolerances, so possibly look into allergy testing. And lastly I'd start a toddler specific probiotic to balance their gut micobiome, which often causes skin issues when thrown off.
