Stay at home mom question

For those of you that are SAHM - do you have background noise or is it silent?

I’ve always had the tv on or the music channels for background noise. However, now that I have a LO im so worried about the background noise of tv causing delays in my LOs development. I don’t let him sit there and watch it but he is very interested in the movements and I’m worried I’ve caused him to be this way because the tv was on in his newborn stage.

I’m putting it on mute or turning it off when he’s awake but how are you all not losing your minds to silence? It’s too quiet in my house... advice please.
