Help?!?

Kayla • 22. Army wife. Fur mommy of 2. Baby Evans 8.20.2016
My LO went to the doctor today and got her shots. That was at 820 this morning. It's been almost 12 hours and she has only eaten about 8 oz. She will not eat, bottle or breast. She has a slight fever and all she wants to do is sleep. Is this normal?
