My son is of similar age and we have a big problem with lying too. Part of it is age (children are exploring what they can get away with) but a huge, bigger part is to to with trauma/how he processes the world. Here is a few examples:
boy runs through the hall and knocks over the coat stand. I ask boy to pick up the coats. Boy: it wasn’t me. Me: I didn’t say it was you but can you please help me pick them up? Boy: but you are blaming me, you’ve said it’s all my fault, that I knocked it over. Me: no I didn’t but can you help me clean it up, I don’t want anyone to trip. Boy: why should I clean it up, it wasn’t me. Ask the person who knocked it over. Me: fine, you knocked it over. Boy: told you, you are blaming me! Me: I don’t care who knocked it over but it would be easier if you passed me the coats. Boy: screaming, shouting, calling me all sorts of names. Me: maybe you need to calm down. Boy: storms upstairs and me take a big sigh,
head in hands thinking, why???? After sufficient time, me: hey, what was all that about, boy? Boy: you blamed me for knocking over the coats. Me: I didn’t initially, I wasn’t fussed about the coats, these things happen. It’s gravity, always catching us out. Boy: I didn’t know I knocked over the coat stand. Me: I know. Really the coats aren’t a big deal, we just need to get them off the floor and it’s easier if we work together. You made that so much worse for yourself, you know. Boy: I know, I’m sorry. Both go and tidy up coats.
the problem with this lying, is that boy has sensory processing issues and didn’t feel when he bumped into the coats. Then add in the trauma response and we have a recipe for disaster. I avoid this as much as possible.
second example, playing at the park with a friend. Boy goes to snatch bucket from friend, friend jerks away and spills it over another child. Other child starts crying. Mum asks what happened. Boy says: it wasn’t me. It was friend. Friend says it wasn’t just me, it was boy too. Boy calls friend a liar. This escalates very quickly.
for boy, his reality is, he didn’t have his hand on rhe bucket, so it wasn’t him. However, looking at the scenario as a whole, he influenced his friends behaviour but boy is unable to understand cause and effect yet. Therefore, his friend is lying and he is telling the truth. For him, it’s how he understands the world. I really don’t know how to help with this one!
another example, is boy has eaten chocolate and lies and says he has lost it. Boy: I’ve lost my chocolate, can I have another? Me: how disappointing. I know you were looking forward to it. Let’s see if we can find it together. Go through a big pantomime of looking for it. If we come across wrapper in pocket, (for he will never litter!) call him out and say oh looks like your eaten it already. Mystery solved! And offer more food. If not, offer sympathy and then get alternative snacks.
boy knows if he asks outright, he won’t get another chocolate so worth a try??
if a toy gets broken, we don’t blame anyone (although boy blames everyone else!) and put it in the bin saying something like “we can’t play with it know, it’s sharp and I don’t want anyone to get hurt”.
the hardest one to deal with is the once where he blames others for things. Not quite lying but similar. An example would be he can’t find his school bag so everyone in the class must have stolen it. It’s trying to explain gently that no one would do that and that it’s likely misplaced. This is similar to if he gets hurt. Someone must have pushed him. He often blames the nearest person for causing it. I just reiterate that I would never hurt him but it was gravity pulling him to the ground again.
as you can see, boy has lots of deficits in his thinking. There is a lack of understanding around cause and effect, people and relationships, gravity, sensory processing which makes the world a really scary place because he believes his lies, it’s his reality. Add on the fact he will sometimes make up lies (then believes them), it makes for a lot
of conflict. We remind him to think before he speaks all the time and to take time to try and understand what has happened before blaming someone else/lying/getting angry but it is hard for him and for us. We are trying really hard as a family to support him
hope some of these can relate. You certainly not alone and wow, do I get it wrong so many times a day!
