Dylan has chosen to suck his fingers more than his thumb in this short life of his (still less than four months old even though that seems impossible by my calculations).
One afternoon, he found his thumb, and chose to drink it up.
Did you notice his left hand? It’s like he doesn’t realize his right thumb could be in his mouth without the aid on his left hand. This isn’t very efficient of him, but so far, he doesn’t take his thumb any other way. Is this unique or standard? I ask you, people of the Interweb, answer my call.
