When I went back to work after my leave with Lily I wanted to be able to show people pictures, so I set up a site that would show moving ones. As she got older, I added new sets, and I've since made pages for Anna and Nora:

I thought it would be neat to make another site, though, that aligns these pictures by age:

Give it a try! There's a slider so you can select which age. Currently it's just 0m through 3m, but as Nora gets older I expect to keep updating it.
