I would push her to talk because at this age grunting is not really acceptable and im sure I will be stoned for this point of view .....if it were me and she wants a drink she would have to say cup or water or milk or even please before she gets it pointing and grunting would not be acceptable at this point.....when she gets it she would have to say thank you or ta ta at the very least or i would take it back ....when she is done eating she would have to say all done to get out of her chair and so ....encourage her to say words by not giving into the grunts and pointing you will be amazed at how quickly she will become verbal
