Eeek. Helppppp! Faye has had two bottom teeth for months now, and no issues. All of a sudden I could hear a horrible sound coming from her crib while she was napping. After about 25 seconds of listening, trying to find the reason for the sound..i honestly thought it was something going on with her crib.. i figured out...her top tooth finally popped through, and she was GRINDING HER TEETH. 🙉🙉🙉 It was so bad that I stuck my finger in her mouth and woke her up. She's been awake for two hours now and won't stop grinding. Ugh. It's the worst sound ever! Have any of you had this issue? What do I do? 😣😣😣
