A month or so ago, we were eating burgers and Isaac was staring us down. He is so interested in everything we eat now. We told him that he was too little for burgers, and that he could have a burger once he had some chompers. He must have decided to hurry it along a bit, because he seems to be getting his two bottom teeth right now.
Friday night, we saw the tops poking through his gums, and felt them. I swear. But Saturday morning? They'd retreated! Could barely feel them, couldn't see them.
(Later in the day though, he bit my finger and almost drew blood. They're back!)
