Yes, it is considered emotional abuse for a parent, in this case, your husband, to consistently use derogatory and demeaning language towards their child, regardless of their age. Referring to your daughter as "retarded" or using other hurtful names when she makes mistakes or does something wrong can have serious negative effects on her emotional well-being and self-esteem.
Emotional abuse is a form of maltreatment that can cause long-lasting psychological harm to the child. It can lead to feelings of worthlessness, anxiety, depression, and may impact their ability to form healthy relationships in the future.
As a parent, it's essential to provide a supportive and loving environment for your child, even when addressing their mistakes or misbehavior. Constructive discipline and communication are vital in helping a child learn from their actions and grow into responsible individuals.
If you are witnessing this behavior towards your daughter, it's crucial to take action to protect her well-being. Consider having a conversation with your husband about the harmful impact of his words on your daughter and encourage him to seek help if necessary, such as through counseling or therapy. If the situation does not improve or escalates further, it may be necessary to seek assistance from a professional counselor, social worker, or even legal authorities to ensure your daughter's safety and well-being.
