All of a sudden last night, Micah seemed to "get it." He figured out that he could put his hands on his knees and prop with them to sit (he can't put them on the ground... his arms are so short he ends up at a 45-degree angle). He wasn't doing his typical smiling last night. You could tell he was concentrating hard. I'm so proud of him!
Sorry the video is so dark. My laptop is in the repair yard (aka my brother's house) and we don't have video editing software on the spare computer.
