Two year old twins, actually they'll be three i believe in october so their 2 and 1/2 ( a boy and a girl) Ive babysat for arent talking much, they do know some simple words like hi, bye, momma, daddy, ball, water, cat, dog, clock, ears, eye, no (for nose) and they certainly know how to say NO!!!!and they of course know what it means. But thats about it! The boy says much more then the girl does, she babbles alot, talking in baby talk, I have no idea what shes saying.
