I was under the impression K had picked up a cold. Since the day after Christmas, she has been congested, had a runny nose, fussy, and hasn't slept for more than 1-2 hours at a time. So far, she doesn't have a single tooth and every time someone said "she must be teething", nothing ever came of it. I don't feel anything poking through anymore than normal. If your LO has teeth, how did you know when it was actual teething? And how long did it take?
