What rights does a person receive from birth?

According to the constitution, every person from birth has absolutely equal rights with all other people. When this world appears, the child is already entering the legal field of the constitution, which is spelled out in the state in which he was born. But at birth, a person already receives some basic rights, such as the right to life and the right to medical care. As a person grows up, he has more and more rights and, of course, responsibilities.
