Truth Seekers
Truth - wow what an issue as we bring up kids!
We ALL battle with this one and showing our kids the value in Truth telling even if it means you get in trouble. It really helps if our kids see we have a consistent attitude to this issue. That if you tell the truth it doesn't mean there isn't consequences but try to keep the consequences as "natural" as possible. You mess up a room; you get to clean it up. You spend extra time on a device; you spend extra time on chores or homework. You break something of someone else's; you need to spend your pocket money to replace it, (a good argument for allowing some pocket money for doing chores at home).
Kids respond much better if they can see the logic in the consequences and it helps teach them that whatever we do in life it always has a consequence (something we all need to bear in mind). Also remember to be fair amongst siblings and try to keep any consequences appropriate to their age and understanding, as well as the same for similar ages despite gender.
Above all reassure them of your love and that in telling the truth and working through the consequences they are becoming a better person and that you are still proud of who they are right now, (we all need to know that, especially when we mess up!)
And don't forget kids will model themselves off you! Be a Truth Seeker and let it show when you have to work through your consequences!
