sitting up? what!?

So I was texting Sarah yesterday about how Henry was doing, and she told me he could sit up on his own. Whaaaaaat!?!?! After having a brief meltdown over missing this monumental (to me) moment [and having to work, blah blah blah], I was super excited and so proud of my little stud! Thank you Sarah for taking pictures for me:

Keep in mind Henry is only 12 weeks old. Basically....he's a genius. My baby can totally beat up your baby!!
