3 months and teething?!

K

My hubbys mom said my husband and his bro were teething at 3 months. My 3 month old is drooling like crazy, cranky AF, not eating as much, and seriously sucking and CHOMPING on his fists. What do I do?! I have some cool teething rings (not frozen). Should I schedule an apt? Pic of my cute little drool butt below!
