Teeth!!

So Macie has been drooling a lot the last week or so, and everyone keeps asking me if she is teething. She loves to chew on everything, and when she sticks my finger in her mouth she can bite down pretty hard with those gums. Yesterday she had a runny nose and she didn't sleep very well last night, she just wanted to be held, which is not at all like Macie. And this morning when she was chewing on my finger I felt something sharp at the bottom! Yikes, I am so scared to feed her again! I cannot believe my baby girl is old enough to have teeth, she is growing up way too fast.
