Bite

Riley, how many teeth do you have in there nowadays? Five you say? Yep, that's four teeth in the last 10 days and a couple more on the way. So far, he's got a full rack of four little nubbins poking through on top and one snaggle tooth on the far left bottom. 

 He deals with the pain by gnawing away at bread all day, pulling it across his gums.

Unfortunately, someone at day care also got some teeth and decided to show Riley:

Two days last week he came home with bite marks. But the boy is so chill, he never cried or squawked. I think he just assumed they were playing. He probably went right back to work on his bread.
