This is Brady at 1 month old.
And, of course, this is Marshall at 1 month old.
I know these aren't the great pictures for comparison, but I had trouble finding good ones of their faces at this age. Plus, both Brady and Logan were much larger than Marshall at this age ;).
So far most people agree that Marshall looks a little more like Brady, but I have definitely seen some pictures where he looks a lot like Logan did too. I guess we'll have to wait and see!
