Does your 3 year old ever make up lies?

Not at 3, but my daughter is almost 5 & has lied a little starting this year. I guess it’s normal lol. My son is 6 & lies at times. I think many kids go through a lying phase.

My 4 next month has recently started this xx

Yes and however annoying it is it's actually a really important developmental step.

Yes, my daughter went into nursery and told the teacher I pushed her over (she fell down the stairs in the garden). Then a few weeks later went in and said I threw her onto the sofa, I didn't she was sitting on my knee & I moved her off my knee onto the sofa. Obviously I was questioned by the nursery which was fine. I've told her if she lies her tongue turns black & only grown ups can see it.

Not when she was 3 but at 4 yes. And it’s okay. That’s when you teach them the importance of telling the truth. If my daughter does lie, I’ll say “are you sure? You know mommy doesn’t get upset when you tell the truth” and then she giggles and says the truth. And I don’t get upset because she trusted me enough to tell me it was a lie.

I think they do it to see what they can and can’t get away with. It’s part of growing up.
