Does anyone know what this is?

Kristina DiCarlo • Living my dream life in paradise with my husband and 1 year old. Baby #2 due May 2018💋

My son woke up with this red patch on his face. And has a small one on his shoulder too as you can kind of see in the picture. This morning it was completely flat but now it seems dry and sort of raised when I touch it

Any ideas?

Thanks in advance
