We have a similar situation. Our kid already can have a hard time winding down for sleep at the end of the day, regardless of screen time. My husband plays some low key games on his phone with her, and we both let her see the screen while we play a few songs right before sleep, and those don’t seem to disrupt her heading to sleep. But of course the screen time content can matter—an exciting TV show before bed means she’s romping around the room and being crazy and disregulated. But we also have the same problem if we read an exciting new book before bed… I used to feel a bit guilty about using screens, since it’s supposed to be “not good” but yeah, it works for us! More parenting advice needs the disclaimer “if this doesn’t work for you, it’s ok to disregard it”!
