Changing a Child's Name: Can a Parent Get a Court Order to Change a Child's Middle Name

My question involves name change laws in the State of: Arkansas

My baby's biological father and I are unwed and have never been married. Before our son was born we had discussed several options for names and one was Thomas because that's his grandfathers name. However, I chose to name him something different. He has filed a petition to establish paternity and as part of the petition for custody is requesting the courts force me to change the baby's middle name to Thomas? Is this a real thing? Can I be forced to change his middle name??
