erythema toxicum? 11 day old male

anxious parents here, is this the common newborn rash that clears up on its own or is it maybe hives/something more concerning? thanks in advance! red marks with a white “pimple” in the middle of them. across chest and legs. he is fine in himself, he has silent reflux but no other concerns until now [chest spots](https://files.catbox.moe/4l876i.jpeg) [legs spots 1](https://files.catbox.moe/m465gj.jpeg) [legs spots 2](https://files.catbox.moe/dew4bf.jpeg)
