I feel terrible saying this, but I'm so concerned about instilling bad habits that I don't do any of that...over mothering. I would NEVER hold her until she went to sleep if I didn't think she was teething.
A few days later I was investigating said tooth and found nothing but a ridge in her mouth - and definately not a tooth seeing as it was in the center of the gum line on the top. Oh well - maybe next time. They say that babies teethe between 3 and 7 months, so she's got another two months before she's considered "late".
