I recommend picking up a copy of "the explosive child" by Ross Green. Every child is unique. Some children are stronger willed and less able to control reations to frustrations etc. Temperment plays a role. Your son sounds a lot like my son when he was little. We used behavior charts & positive rewards. We used natural consequences whenever possible .. for example, if he threw the lunch sandwich across the room in a fit of anger .. no lunch. And guess who gets to now clean up.

This is likely to be a long haul of consistent application of natural consequences, specific behavior charts with appropriate positive rewards. Don't give up - your son is worth it and all your efforts will result in a well behaved young man.

Another item to keep in mind is that sometimes a child with learning difficulties take longer to learn a lesson. So don't expect to just give a lecture one time and your son will behave. Expect to repeat repeat repeat - always from the viewpoint that he is not doing this on purpose. But he must change.

Once your son begins pre-school, be sure to stay in touch with his pre-school teachers and share any behavior concerns you have with them. If the preschool is part of your public education system they can arrange for testing as well as behavior support services that can really help.

Hang in there !!
