There is a possibility that you could be convicted of Injury to a Child for spanking your child if you are not found to have used reasonable force in spanking them. Under the Texas Family Code Section 151.001(e), the parent, grandparent, stepparent or guardian of a child “may use corporal punishment for the reasonable discipline of a child.” So, even though you are not always subject to being convicted of a crime for spanking your child, the Injury to a Child statute makes it a crime to cause serious bodily injury to a child because that is not considered reasonable discipline.
