When do I need to start worrying about screen time?

My little guy is 7 weeks old and today is just kind of dawned on me that I almost always have the tv on in our living room during the day. It’s not like I ever sit him in front of the tv, but we spend a lot of time in there. Should I leave the tv off while he’s in the room? I am on maternity leave so I’m not really sure what I would do other than clean the house all day if I can’t watch tv haha. I don’t want him to have any screen time until he is at least two years old.
