I don't remember exactly when DS started talking, but I remember at 8 months old he woke up in the morning and said Daddy. The next morning he woke up and said Mommy. The next morning he said Daddy and then he called both of us Daddy for the next 3-4 months. But he would smirk every time he called me Daddy. We tried signs, but he only learned a couple by the time he could speak the actual words. I think he was speaking in sentences about 13 months.

He crawled a perfect 4 point crawl at about 4.5 months (after which he stopped crying in the afternoon). Then he refused to walk until about 14 months. I think it slowed him down.
