What is this??

Amanda • Wife and a mommy to Evan (6yrs) and baby Ethan 😊

For the past 2-3 days I’ve been finding these on my 2 year old. They are not all over but I’m noticing they appear randomly. He has some on his upper thigh, wrist as shown in picture and one on his back. Tried calling the night nurse hotline number but it’s taking way too long. I’m going to call first think in the am but I was wondering if anyone knew what this looks like. Doesn’t seem like they itch or bother him.
