Absolutely sick to death of DS1, 10, and DS2, 8, fighting. They have massive arguments on a near daily basis over Fortnite which result in them screaming and hitting each other so that Fortnite gets banned (probably a good thing) but also start rough housing when brushing their teeth, messing around, being really loud etc etc. This evening the TV was switched off and I sent them upstairs to the bath which they decided to share whilst I tried to settle DS3, 7 months. DS3 is just falling asleep when I can hear screaming and messing from the bathroom, so loud that is wakes DS3 and I fear that one of them is going to really hurt the other. Gave them a massive telling off but it will be the same thing tomorrow. Their table manners are also atrocious, despite me constantly reminding them. Feel like I am constantly telling them off to no effect. DH (who is not DS1 and DS2's dad) has given up and says they are so badly behaved that he doesn't want to interact with them so I am left to try to manage them. They are a million times better when they are not together so wondering if I need to do something drastic like alternate nights at their dads, just so that they are not together. DS2 is angelic at school; DS1 is not very well behaved. Feel like I am failing as a parent. Can anyone help?
