6 month old

Thoughts on tv time? My LO is 6 months old and LOVES watching tv. Almost to the point where she doesn’t even want to play by herself and I want to cut tv out completely. She hasn’t rolled and isn’t sitting up on her own and I’m almost wondering if it’s cause she was watching tv too much. 😭😭 Her doctor isn’t concerned that she isn’t sitting or rolling but I am for some reason. Thoughts?
