I'm just going to be honest here. About a week ago, we brushed the kids' teeth for the first time in about a month. (Hey, they lose these teeth anyway, right? No big deal.) Well, when I was doing this, I noticed that Miles had some big molars coming in on the bottom. I have no idea whether they're coming in on the top, too.
Anyway, I guess that explains some of the fussiness and the extreme drooling that has been happening around here.
