A niece is the daughter of one's sibling, which means she is the child of your brother or sister. For example, if you have a sister and she has a daughter, that daughter is your niece. Nieces can be a source of joy and connection within families, often forming close bonds with their aunts and uncles. Nieces can play various roles in family dynamics, participating in family gatherings and celebrations. They may also look up to their aunts and uncles for guidance and support. The relationship can be nurturing, as aunts and uncles often enjoy sharing experiences and creating memories with their nieces.
