We expected it from birth since DS comes from a family with many talented people. One grandfather has a math formula named for him and both parents are smart.
1. It stood out around 6-9 months (don't remember exactly but it was before he started walking at 9.75 months) when he made us spend 30 minutes repeating the specific pronunciation of animals in a book. He was sitting on his mom's lap and moved her finger from picture to picture and then looking at us for the word. We thought it was random until he started going back to pictures we'd already done and trying to repeat the sounds. Then after 10 minutes on one page, he turned the page and started again. Then he went back and forth between these pages working on getting the sounds right. It was so focused and for so long it caught us off guard.
2. We treated everything as normal. Ds has older gifted cousins and we have a skewed sense of normal.
3. We don't know for sure but we're pretty confident he is.
