A proposed law banning the smacking of children is set to be debated in the Senedd for the first time later.
The Children (Abolition of Defence of Reasonable Punishment) (Wales) Bill was introduced in March.
The Welsh Government says the purpose of the Bill is to help protect children's rights.
Some critics say the law will divert police resources away from other crimes, other say the law interferes with parents' freedom to bring up their children.
If passed by the National Assembly for Wales and it becomes law, parents and other adults acting in a parental capacity will no longer be able to physically punish children.
The debate is the final part of the stage one process, which has heard evidence from a variety of organisations and representatives including the police, local authorities, children's services and health services who have all backed the bill.
It has also received support from a number of children's charities including the NSPCC, Barnardo's Cymru, Save the Children, Action for Children and Children in Wales. The Children's Commissioner for Wales has also welcomed its introduction.
