Thoughts?

I’m not looking for medical advice, just your thoughts on what this could be… I noticed at the store around 630PM and I will be calling his pediatrician first thing tomorrow. He was outside with hDad today… I’m thinking ant bites? My husband says he didn’t notice this while dressing him for the store, so I can’t say for sure it’s bites from outside.

I have checked him Head to Toe. No other spots. I have checked his mouth. Nothing. Just what is pictured
