Children can be seriously hurt by parents who think it's OK to smack them, reports show.
A group of MPs and children's charities are calling for the laws to be tightened to keep kids out of danger.
School teachers are already banned from smacking kids, and from September, childminders will be stopped too.
But some campaigners think parents should be banned as well.
Around 80 children die every year from physical abuse in the UK.
The campaigners reckon abusive parents use the current law to excuse themselves for hitting their kids.
But the British Government is worried that if it bans smacking altogether, it'll be seen as interfering in family life and most parents won't like it.
The National Society for the Protection of Children says smacking should be stopped.
