My suspicions were correct. Today I finally felt it as well as saw it, a sharp little point just peeking through her lower gums.
I’ve been giving her some children’s Tylenol because she’s seemed a bit cranky. I tried to give her a cold teething ring that I bought today while out running errands. She was fascinated with her new toy but didn’t put it in her mouth at all that I could see. However, she did very much enjoy the stalk of frozen broccoli I gave her to munch on at dinner.
