Adoption is when a child doesn't live with their birth parents, but they find a new family who will take care of them forever. Just like when you meet new people and make new friends, some families want to love and take care of a child who needs a new family.
In adoption, the birth parents choose to give up their right to parent the child and the new family, called the adoptive family, goes through a special process to become the child's new legal parents.
Adoption can happen for many different reasons. Sometimes, the birth parents can't take care of the child because of big changes in their life like sickness, death, or other big problems. Sometimes, birth parents might have problems with drugs or alcohol or might not be able to take care of the child in a safe and healthy way.
When a family wants to adopt, they have to go through a special process to make sure they can take good care of the child. This usually means they have to fill out paperwork, go to meetings, and meet with special people who make sure they are ready to become parents.
Once the new family is approved to adopt a child, they become the child's legal parents and are responsible for taking care of them forever. Adoption can be a really happy thing for everyone involved - the child gets a new family who loves them, and the new family gets a new child to love forever.
