alternatives for corporal punishment for children

Take away their privileges -- that's a common method here in Sweden because corporal punishment for children is against the law. Embed the idea that their leisure activities/toys are privileges that can and will be taken away if they misbehave. From what I observe, it does work to a certain extent, especially for older kids who are pretty much obsessed with their toys and gadgets. As for younger kids, give them a time-out and tell them that they won't get treats (their favourite snack perhaps?) if they continue to misbehave.
