Children become adoptable for many different reasons. Sometimes the birth-parents are not able to raise the child. They may be too young. They may not be able to give the things a child needs to be happy and healthy. Sometimes the birth-parents have died.
People adopt children because they love children and want to bring a child into their family.
Foster parents, the birth-parents family, or anyone else who wants to include a child in their family can adopt children. Adoptions can involve all types of children and families. Children can be adopted at any age. Some are babies. Others are teenagers.
