My daughter babbles a lot in her own language.

But she seems to only know mommy, daddy, deer, cee cee (grandmas name) bubba (water cup) shoes, bye, hi, chair, bear and boots. When I ask where things are she knows exactly what I am asking of her. In any of her books I ask her to point to the raccoon, or where is the purse, and she knows all that I ask. But she’s not very verbal. And especially quiet around people she doesn’t see often. Should I be worried?!
