At what age did you stop having adult shows on TV with your kid in the room?

My girl is 13 months old. We have a no screen policy with personal devices - she doesn't get our phones and she's never seen an iPad, and she won't until she's a teenager. But we do often have the TV on as background noise while she plays. She doesn't watch it - the most she'll do is stop and dance to a theme song and then go back to playing. I'm not worried about the TV as a concept and I don't even really count it as screen time because it's so far away, can't be manipulated by her and can't leave the house with us. But I do wonder at what age I should be more careful about what's on the TV while she's in the room. I've watched a loooot of Grey's Anatomy the past few months and right now I'm rewatching Gilmore Girls. When my husband has her, they usually watch Lord of the Rings. When did y'all switch over to kids' shows? I will obviously do it at some point, if only for the whole social aspect of it when she's old enough to bond with other kids about things like Bluey or whatever, but I'm dreading it. Ms. Rachel's voice makes me want to peel my skin off (she is an absolutely lovely person but I cannot handle the tone she uses).
