It seems that ur hub is doing it for a while already. I will look into how often he hit the toddler, how hard and what situation. Issit for discipline or abuse? By filing a report, ur relationship with ur hub will be soured but it might also deter him to physically hit the toddler. Warn him of the consequences and act based on what is the best for your child. U might also want to teach ur toddler to stay away from father and to keep him close to u as u r his protective figure.
Tell your husband that there are other ways to discipline a child besides using physical force. Moreover, at a toddler age, nothing he does, no matter how naughty, warrants a beating. I suggest you tell your husband that he can get into a lot of trouble if someone reports it to the authorities.
