Could this be eczema on back of toddlers legs ?

AJ • x2 🤍👼🏻

I’ve noticed these dry patches on the back of my daughters legs for about a month now, we saw her pediatrician about 2 weeks ago & I showed him some photos similar to these & he said it “could be eczema” it starts to get a bit better for a couple of days then goes back to this. Anyone elses toddler have something like that ?
