[Esme's Mommy]

I just found a scab on the top of Esme's head. It's right in the center, where her hair parts. It's kind of pink. I just called the vet to make an appt because I am such a paranoid mommy, but they are closed already. What could it be??? An allergy? A bite?? Anyone else's baby have one?? Hopefully, I can get her into the vet on Monday.
