Z.A.
Yay! Her imagination just stated kicking into gear :) :) :) This is actually a sign of a very very GOOD thing.
As Peg and Judy said, you deal with this, by not putting them in a position of being able to lie, and by modeling honesty.
At THIS age, kids frequently do two things:
a) tell you what they WANT to be true
b) hyperfocus on one aspect of something that happened or alter what *really* happened to describe to you how they *felt* about what happened
a) can be things like telling a neighbor "I had to go in an ambulance to the hospital!" (because they think it would be the funnest thing ever -yes i know that funnest isn't a word...but it really nails how THEY feel about it-). The story that they imagine can get quite detailed, and can change at the drop of a hat (they fell off the roof, they were sick, the broke their leg), whatever their imagination tells them would be a reasonable and interesting thing to have happened.
a) can also be "I didn't take the cookie" with the cookie in their hand, because they SEE you're upset, and that's the worst thing in the world to them (our being sad/angry/disappointed in them). So...no WAY would they have taken the cookie...actually translates into "I would never do ANYTHING that would make you sad, mommy". Which is about the sweetest thing in the world, not the trying to not be in trouble thing that an older child would do.
b) Can be things like picking your child up from preschool and having them tell you that all the kids were throwing rocks at him. If you know about the "substitutiary locomotion" thing that happens, you can ask if they were REALLY throwing rocks at him, or if that's what it FELT like. (Ahem, you can also get the lowdown from the teacher...which is why it's sooooo important to have preschool teachers who you trust, and who are paying attention". The throwing rocks at him, in my son's case, was actually that - his feelings had been hurt & he felt like curling up in a ball to protect himself & he felt sad and scared and angry and afraid (like anyone would if all of your friends started randomly stoning you!) He wasn't LIEING about being stoned, he was trying to say how a non-stoning situation had made him FEEL...and that was the best way he could convey it. I suspect he also knew that the idea of him being stoned en masse was something that would get my undivided attention...which he also wanted. So not lieing at all, but miles and miles away from the "truth".
b) can also be things like "my daddy's never home" or "nana yelled at me all afternoon" or "my mum doesn't x" or "my friend did y". or "i want scrambled eggs for every meal" or or or. None of which would be true if taken as an absolute statement. These are the kinds of statements that tell you, again, how your child feels THAT MOMENT about a situation. These are the kinds of statements that call for both examination and further detail.
Three more tricks:
- We (the parents) are still omniscient at this age, and they (the kids) are pretty literal (oddly enough). It's best, I've found never to ask the classic "What are you doing???" thing to a toddler. It seems to send them into a kind of a shock. The "well I had THOUGHT I was painting on the wall with lipstick and maple syrup. But if MUM doesn't know what I'm doing, maybe I'm NOT doing that. If I'm NOT doing that WHAT AM I DOING??? I DON'T KNOOOOOOOW." Whereupon we get the classic answer "I don't know." Which, by then, is actully true. They had THOUGHT they knew what they were doing, but no longer. So it's better to ask "WHY are you shaving the dog, sweetheart?" if you want an answer to your query. If you don't care why they're shaving the dog, or painting with lipstick and maple syrup you just TELL them "Honey, we don't use mummy's lipstick or food on the walls. If you want to paint, we can do it on paper or on the GLASS door...but only after you ASK to paint, and only with paint/etc."
- Ask leading questions (also why toddlers aren't usually allowed as witnesses in a trial), instead of open ended ones. For example...back to the "all of my friends were throwing rocks at me all day" gets the series of questions about "Did that really happen or is that how you felt?" "Did that make you scared? Did that make you angry? Did that make you x,y,z." You have to be REALLY careful about this one...because leading questions CAN imprint your own views instead of finding out theirs. For example it's waaaaaay better to ask if they had fun, than to ask if something was boring or sad or hard or lonely, OR exciting rather than scary...THEN to ask the opposite. IF you get a yes to both, you can ask if something was exciting AND scary, or just one. Sometimes kids make mistakes, (especially with emotions that are close...sometimes they just hadn't thought...and sometimes they feel happy and sad about the same thing, just as we do. I always lead with the positive, but accept the negative. Many parents I know do the opposite, which seems unfair, as that teaches kids to look for the bad about something before the good.
- Model honesty, but don't expect OUR version of honesty yet.
Obviously, if we aren't modeling honesty, they won't know what it looks & feels like...but 9 times out of 10 that fantastic lie they've just told IS them being as honest as they can be. If you shut them down on that...rather then investigating and rewording...that actually teaches them NOT to share with you. AKA to withhold and to lie (for real, lieing). So patience. This stage lasts for a few years.
