回复：想请问知道的各位，丈夫和前妻的未成年儿子由丈夫抚养，那么

I think if the hu*****and has full custody of the child, the other guardian should be the stepmother. If the hu*****and and the child's mother share custody, then the other guardian should be the child's mother or an agreement between the stepmother and the child's mother.
