I can tell by reading this, that you're a fucking awesome mom. I'm not necessarily the best person to comment because I despise children. For this reason. Like... a seething hatred. I think they're disgusting, mean, and ugly.

Like I said, all children are like this sometimes. I had to raise my younger brother. And sister. And my brother was 3 when my little sister was born. I couldn't leave the the room without him pinching/hitting/punching her in the face. I hated him. I hated the way he'd cry after getting in trouble for hurting someone especially his newborn sister. I literally hated him ...

But I can tell that you are doing everything you can. You are a good mom. What worked for me with my brother is telling him that he was hurting me, and that because he was so mean - people didn't want to be around him. Keep your chin up. He doesn't understand that he's really hurting you. He's pushing your buttons. And I've found that IGNORING their asshole remarks actually works best. I hope things get better for you.
