Idk what to do

Mellissa • Wife & Mommy 🌺 Preggies: #2 ❤️

So my 3 MO has been SO FUSSY since yesterday. She has a low grade fever after we have her a warm bath. But that was it. She was tossing and turning all night & dream fed every hour. I don’t think she’s teething (no other signs of it) but Idk what’s wrong. Anyone go through this?
