My youngest started out that way (actually smaller, was a premmie). Great photo.
If he's yours, keep using the camera; they grow so quickly. Stick the exposed film in the fridge, and you should have the energy in about 8-12 months to process the backlog.
Yep shes mine, and I had a backlog before she was born. I might just end up shooting more color and sending it off for processing just to not get too far behind.
