IT'S A GIRL!
We are all excited--most especially Benjamin who has been asking for a baby sister ever since Seth was born.
Here are a few recent pictures.
This one encapsulates the relationship between Benjamin and Seth. They love each other and love playing a mock "rough and tumble" (Benjamin is remarkably gentle and also tolerant of what Seth does to him!). 
This is one of several darling pictures of Seth and Justin on the swings. Seth loves his daddy!!
Marianne took some photos of just Justin and me as well. We are still very much in love!!
For the last week or so, Seth has been starting to take steps independently. Now he is starting to put more steps together and his balance is quickly improving. Today (I'm surprised myself that I got this posted the day I took it) he walked all the way across the living room and I got a video of it! He is also starting to say some words--bread, water (wa), all done, all gone and the other day he said Ben!
Enjoy!
Seth has learned how to climb the stairs and does quite well. We are still working on going down safely. He doesn't want to turn around and go down backwards--he'd rather try head first! (Luckily I've prevented him or caught him.) When I do get him to go down a stair or two backwards, he suddenly decides he'd rather go up--that is the way he is facing after all!
He has learned to climb much faster since this video. He can make it up the stairs in 30 seconds. If I turn my back for a moment and have forgotten to put up the gate, he can be three-quarters of the way up before I turn back around, notice he's missing and go after him. He loves climbing!
