Probably the best guess of a 15 month old's IQ is the parents' IQ.
Mom (me): no I'd say not gifted, though I was told I read early (don't recall). Dad is currently getting his PhD in Economics, but he's never been tested or anything. Maybe we just have a smart little cookie and not anything too out of the ordinary.
I'm basically saying it's too early to tell. Even testing at age 4 or 5 is quite unreliable, although it is said that parents' assessments are more reliable. Nevertheless, you can try to create an environment where a child can reach their potential, even if you're not sure what their potential is. (School's should try this idea too.)
