12 month old has rash? Or bites?

Clarissa

My 12 month old has what looks like a rash or maybe some kind of bug bites on his face, could anyone tell me what it is or could be? It just happened within the last couple days an the redish pink marks aren't raised. My mom said she thought maybe it could be flea bites from one of our dogs having fleas? Or bed bugs? Any suggestions are appreciated
