Lectured my 6 year old and told him he's showing signs of a criminal.

Oh man... not my best parenting moment. I want to cry so badSo my son lies a lot. He has since he began talking. Mostly to get out of trouble. And I'm tired of it. He always sneaks things in his pockets (gum to school when he's not supposed to or toys he's not supposed to) and the teachers always tell me about it. Or lies about cleaning his room but then lies about bigger things as well.There was an incident at school yesterday where he was being chased by a group of boys and he said one tripped him and was bullying him. A teacher said they saw him fall on his own and not trip. So now there's an investigation type thing. I talked to him about it and couldn't really get a straight answer so I stressed to him how important it was not to lie. That bullying is a big deal. That was last night.Then this morning he tried to sneak mints into his pocket before school and lied about something else to my face and I called him out. I said "you're 6 now. It's not cute to lie. And if you were lying yesterday about the bullying you need to tell the truth. This is not a game. When you're older you could go to jail for lying. You know who lies and cheats? Criminals. I'm going to start punishing you every time I catch you lying."He currently has a tablet and switch taken away because he would sneak it into his room after bed time. First I caught him with his tablet and I told him it from him and was planning on punishing him the next morning but i was too exhausted to say something tight then. Then hes telling me "mommy I need water" so i told him to go get it and he goes and sneaks his switch in his bed and I catch him with that so I took them both for a week. The kids who were playing with him yesterday weren't the same kids so I don't think it was true.I don't know if he's telling the truth about the bullying or not. He told me two kids punched him at school and I talked to the teacher and they said they would keep an eye out. I told the guy doing the investigation about that incident as well and I just want to know the truth.If he's lying about the bullying then I'm doing the right thing by lecturing him and making sure he understands that it's a big deal. If he's being bullied I'm not supporting my son like I should. It's eating me up inside. I told him about the boy who cried wolf and how one day I won't be able to believe him and now here we are. He says stuff and I don't believe him.Does anyone have any advice? I feel like such a bad mom. So much guilt. Please help. via /r/Parenting https://ift.tt/2CJuf8o
