But then I remembered the photo album* that my mother-in-law brought me a few months back and now it's all very clear.
I snapped this pic of Lincoln a couple of weeks ago.
And this one is of his daddy, at around four months.
I know! Right?
But wait. It gets better!
No, we didn't stage this photo. It's pure coincidence that the composition is so (eerily?) similar. And clearly, those genes are powerful. He's definitely his daddy's boy. Mystery solved.
*You might recall this little gem that I posted before.
