I sense that Finn is on the brink of something. I notice subtle things lately, like he's becoming more frustrated when he can't reach a toy he wants up on a table. I think the motivation to stand is finally beginning to take root. He's not standing yet without help, but I get the feeling he's thinking about it.
His babbling seems to have become more meaningful lately, too. No words still, but he's definitely become more expressive with his babbling, with different facial expressions and the cadence and intonation of his voice, like he's trying to get some point across. Sometimes it appears that he's trying to mimic one of us singing.
It's fascinating and wondrous to watch these baby steps, to watch it all unfold so slowly and meaningfully.
