Is this normal?

My baby puked while on her back and when I noticed I flipped her on her side..it came out of her nose as well as her mouth. I went to change her outfit and she was crying hysterically cause she scared herself. After she was finished I took this picture and this is what was there..it’s slowly fading away now so I don’t think it’s an allergic reaction but could this be from her crying hysterically?
