My sons embarrassing me by refusing to stay in school

He’s 6 and I love him more than life itself. He’s usually a happy kid and smart, never any problems in school behavioral wise or academic. Except he’s started doing this thing when I drop him off and doesn’t seem to show signs of stopping .He latches onto me and refuses to let me go back out while he walks to class like he’s supposed to. He will cry and refuse to walk to his classroom. I can’t walk him there myself (security reasons) so I end up in the lobby standing there awkwardly with a kid behind me latched onto my arm like a baby. When security or counselors approach him to see what’s wrong and they’ll talk sweetly to him to convince him to go he will just hold on tighter. His friends will pass by and say hi to him and he will just ignore them. This is the third time he’s done this to me since the start of school three weeks ago. It’s infuriating because I also have to take my pre k daughter to her class and have to drag his clingy ass with us crying the whole way. My daughter isn’t like him at drop off but is starting to pick up his horrible attitude towards school. She’ll now say things like “yuck school..” Today, trying to be nice I even let him ride his bike to school to brighten up his morning. But as soon as we got there he got off his bike and latched onto me like his life depended on it. If I told him to sit in the lobby and I walked out he ran after me crying.I’ve tried time and again to find out if he’s getting bullied. If he’s ok in class or if something or someone is making him uncomfortable. He says no one bothers him he just hates first grade. He says it’s not fun like kinder was. That in first grade all he does is write and do math and that it’s boring and he hates it. Today he ran out the door behind me sobbing in front of the other parents and children. It was embarrassing and I was trying so hard not to raise my voice and scream at him to get his ass back in the building. I ended up taking him back home. And as soon as we returned screamed at him to march his butt straight into his room and told him I was taking his tablet away and I don’t know when I’ll give it back. I told him he can’t watch tv all day and only to come out to use the bathroom or to eat. I’m already getting dirty looks from my mother ( whom we temporarily live with) for punishing him. I don’t think I’m taking this too far. But my blood is boiling atm still and I’m fed up with this. I’m tired of security guards looking at me and rolling their eyes the minute they see my son is about to start his shit. I’m tired of his whining and crying. He’s lucky I currently don’t work or I would have been fired by now with how long it takes for me to drop him off if he lets me at all. Ugh...please any advice would be great. via /r/Parenting https://ift.tt/2Q1WW4H
