Here's the Proof!

I realized I didn't actually have any pictures of Lucas sitting up, so in case you didn't believe me, I took a bunch!

 "What's big sis doing?"

 Not sure what that face was about!

 Happy boy! He loves to slap at the ground or the toys in front of him.

  Leyla was posing, according to her...although I don't know what she thinks she's doing, with her hand up like that!
