How do i know if my baby is a genius, even though she can't talk yet?

Time will tell: Watching the development of one's children is awe inspiring. The fact that two cells can become an individual is amazing. Encouraging learning and interaction from an early age is a great way to stimulate their little brains. You cannot reliably test you baby at such a young, but give them the benefit of the doubt.

Genius?: I am afraid it is much too early to determine genius status. Follow her developmental progress closely, comparing her progress with standardized results for age.
