My 5 year old DS has been capable of lying for a long while now, but it’s starting to cause problems as he’s started accusing others of doing things that aren’t true. It’s usually when he’s upset, so I see it as a form of lashing out almost.
A example is we were on holiday recently and his older cousins were leaving him out a bit, and so he accused his younger cousin of calling him a really nasty name. There’s no way it was true, and the DCousin was getting more and more upset at the accusation, but DS wouldn’t budge.
He also accuses DS1 of things too, which is very tricky as DS1 has ADHD and some of the things are true, but not always, and DS2 is so deadpan when he’s lying that it’s hard to know what’s true and what’s not.
I’ve tried to explain the outcome of it in a social story, asking him how he would feel if I told his dad that he’d kicked me when he hadn’t, for example. But I’ve had to be really stern and say you must not lie, if it happens again DH and I will be very cross (he absolutely hates being told off).
Does anyone have any tips that have worked?
