How would you handle it

I wouldn't want my child watching his screens anyway. If he wants privacy, maybe you can have a barstool or somewhere higher up for him to sit, so this is not an issue. I wouldn't put it all on him to manage. He's 7 and just trying to play his game. 🤷‍♀️ Usually it's a good rule to have to share things when you're in the common living room, but if he's not allowed to have electronics in his room (which is an even better rule) it should be an exception. He is allowed to have some privacy as long as he is behaving appropriately.

Honestly, I am all for having your own privacy and etc, however, I think bc they are siblings they need to learn to be together, share, respect each other. If it was another random kid and he was doing that then I wouldn’t say much to him but because this is his sister, I would share with him that your sister wants to watch with you and what you are doing. Remind him that she is doing that bc she wants to be close to him and enjoy his company when he is not there and has to go to his mom’s home. I can relate to this bc I have SD8 and she does this exact thing with my son who is 2. The age gap kinda gets annoying bc they are obv at different stages, but I think about myself and how I would treat my siblings in this matter, & I was always taught to treat my siblings with respect, love, care, etc and to show them the most love bc at the end of the day, we are all each other has when our parents are gone. Eventually the toddler is going to get bored and do their own thing anyways.

I would just tell him that if his little sister is bothering him to let you or his dad know and you will have her do something else.

I would just give him his space. Don’t stress it let it go

I don't think he's necessarily being rude, just wanting his space and she's probably is in his space, obviously not meaning to bc she is 1 but you have to remember there is a huge gap between them plus he's a boy and she's a girl. Like my brother didn't want anything to do with us girls and we're only 2 years apart, but that's cause he was boy and we were girls. There's an age gap and a gender difference, I wouldnt stress trying to get them to play together or even interact that well together bc odd are it's not gonna happen. Maybe it will when he is a teenager but not at this stage. He's learning his boundaries and space and sometimes we as parents just need to respect that.

Does he bond with his sister in other scenarios? I think if there was no bonding I would be more focused on that as a whole and less about the video games. Siblings are rude to one another and in my experience that will happen until they are adults haha. As long as the foundation is set: kindness, family, love etc. He’s acting like he’s 7 and he’s allowed to not want his 1 YO sister in his space while he’s doing something he’s focused on and enjoying. I agree with Bonny, I think she’s giving sound advice. I also think when kids are on screens too much they become more irritable and forget their manners. Sometimes a reset is needed but I wouldn’t frame that with little sister connected to it or else he may be resentful.
