Hello, I just need a sense check please. I have 3 children (DD 6, DS 3, DD baby) and my older two argue multiple times every single day over absolutely meaningless things that I cannot anticipate. For example, it was time to turn cartoons off - they fought over who gets to turn it off so DS ran to turn it off at the plug, but DD had already managed it on the remote and then he cried and tried to hit her, so then she cried. DD was drawing, while DS found her whistle and started playing with it - immediately she said it was hers and she needed it and she “she was going to whistle while drawing”, so she tried to snatch it from him and he bit her and then both cried. Today, DS finished brushing his teeth just as DD finished going to the loo, so they both needed the sink, he did his thing and turned the tap off but she hadn’t finished washing her hands so she turned it back on, but he turned it off and so on with much shouting. And on it goes. Is this within the realm of normal for young siblings?!
