Well I felt like a terrible mom on this day...
A couple days prior, Noah started to slobber and drool. I thought, Hmmm, he must be starting the teething process. Literally, two days later, he had two little teeth. No muss, no fuss. And I hadn't even noticed. We were at a friend's house and I mentioned to her that I thought Noah was going to get teeth soon. She had her finger in his mouth and said, "I think he already has teeth".
He was exactly 4 months old; the same age as Finn when he got his bottom two teeth.
