little bumps around the mouth?

Angelina • 26. 9 years w/ my love. Married 💍 I'm an artist, nature lover, Crystal collector, mommy to 2 doggies and our babies, Lilliana 5/26/16 & Elena 5/10/19
kinda hard to see in the pictures with bad lighting and a tired cranky baby that didn't wanna be still but I noticed the other day my daughter is getting these little tiny slightly red bumps at the corners of her mouth? what would cause this?
