You have not provided enough information so that I can provide you with a useful response. If you and your mother reached an agreement between yourselves, without a court order being issued in the process, then it's a simple matter of you simply taking custody of your child back with or without your mother's agreement. If you and your mother made a guardianship arrangement through a court, then you and your mother need to terminate the guardianship arrangement.
