10年前,我父亲收养了一个1岁左右的女孩,当时,我父亲已经有两个孩子了,而且,也没有与女孩的父母签订任何协议。现在,这个女孩已经11周岁了。前不久,孩子的亲妈再次出现了,于是,我父亲不想继续抚养这个孩子,想将其送回去。可是,她的母亲不接受。请问:我父母对这孩子进行的抚养算不算是收养关系?收养,是指公民依法领养他人子女为自已子女,从而使收养人和被收养人之间建立 Ten years ago, my father adopted a girl about one year old. At that time, my father already had two children, and no agreement was signed with the girl's parents. Now, this girl is 11 years old. Not long ago, the child's mother appeared again, so my father did not want to continue raising this child, want to send it back. However, her mother did not accept it. Excuse me: Will my parents take care of this child as adoption? Adoption refers to the adoption by citizens of their children as their own children, so as to establish a relationship between the adoptee and the adoptee
