I'm afraid, however, that she isn't always aware that what she's done is wrong. Later, she seemed almost excited to tell her daddy what she'd done. A. Probably not. Young children may have a general understanding of their actions, but not really comprehend the full significance of what they have done. It will be a few years before they can make the leap to understanding the feelings of others.
Preschoolers gather clues about what's right and wrong by watching our responses to their behavior.
Your daughter will also gauge the seriousness of a situation by what you do. For example, if you punish her by telling her to go to her bedroom which is full of wonderful books to read and toys to play with, she may not understand she's done something wrong. However, if you tell her to immediately turn off her favorite television program because of her behavior, she'll probably get your point. Take the next step and teach your child what right behavior looks like. Then just before Grandma's next visit, remind her of what you talked about.
