Family has a different meaning for every person
For some a family may be just parents and children. Some extend the meaning to grandparents, aunts and uncles. For some family includes individuals, grown together and knitted close as if they are blood relatives.
Some families also have special challenges and circumstances. A parent may be on military deployment. A grandparent may be raising grandchildren. A family may only have one parent living at home. There are physical and learning disabilities that can complicate difficult situations.
Each family is different and has unique circumstances and challenges.
