Thanks for the answers.
Chay, what were some of the eyebrow-raising stories? My mom cautioned us, that if DD did something like reading or math at an unusually early age, that we should probably keep it to ourselves. Like you said, without previous experience, it's hard to tell what's defies your expectation as a new parent and what just defies expectations.
When DD was closer to 1, we were playing at the library. On this day there happened to be another child there that was actually close in age to DD. The other child was walking around. DD wasn't walking yet. I asked the other parent how long the child had been walking. About a month. We kept on playing. A little bit later the other parent asked how long has she been pointing at things?
So all kids are different.
