3 Year old & Lying.

I'm so annoyed with life sometimes. I think I just need a new hobby that's all. I think I'm gonna take up crocheting again. I really wanna try and do some sewing. I literally need a place to put all my frustration. Besides, I'm NOT patient. But, I seek the outcome and I do it. But, let me tell you, I'm not patient for beans and it drives me nuts that I can let myself get to the point of giving up. So annoying.

Anyways! So, according to my title - plain & simple. My daughter, she's only 3 years old as of September, she's got this thing of wanting to "LIE" all the time. Yes, NOT telling the truth. We don't lie to her or show her that lying is okay. You know? On a daily basis, I'm teaching her that lying is for bad girls and that there is consequences for lying. Let me tell you what she's lying about. See, I'm a vivid diaper changer. Yes, my daughter still in diapers. (No judgement please, I don't have time for that). But, anyways.... she use to tell me all the time that she's gone #2 now when I ask her if she's gone in her diaper - she tells me "NO" but there is.

I don't know what to do about this lying. I mean, it's just a bowel movement but still - i'm telling you this because I'm just irritated that I can't find the way to have this lying STOP. I'm teaching her that it's not right to lie that GOOD GIRLS don't LIE!!! I've taken away her toys, her favorite of "toy story", her DVD player, everything. I don't know what to do.

I need advice.

Do you have a child  lies?
How old is he/she?
And what is that she/he lies about?
What is your way of discipline?
