Awhile ago, Jacob looked like this:

Now he looks like this:

Every year around Jake’s birthday, I get a little freaked out by how much time has passed. I also sometimes can’t believe I have managed to get him to this point with no major terrifying incidents. (There’s still time, I know.)

Where is the time going?

Congratulations on 4th grade! I’m glad he survives what appears to be his crucifixion when he was a week old.
