My little baby looks so big all of a sudden!
For those of you who still don't see Sean in Colin I'm hoping this helps. Unfortunately I caught him in full flash, but the eyes, ears, lips and expression are all very much Seans. It is one of the most Sean-like photos I've seen.
One of only a few photos of 'Baby Sean' I have here in our apartment (although I have more of him than I have of me!). On the back it says 1981, so the age should be close.
