We have one but only use it when we are getting her ready for bed. She does get excited over it so don’t think we would be able to use it to get her to settle to sleep.
We’ve got one! Can’t say it helps sleep but I think it’s nice to have on 😁
We use one and it has a white noise feature that we use too. I put it on when getting him ready for bed, with the light on the dimmest setting, and it stays on all night. Personally I've found he is sleeping better, but that could just be the white nosie. He sleeps without it, so don't feel it has created a problem yet for us. We use it sometimes in the day for sensory play, in a darker room or under a foil blanket which he also loves. X
We use one when we're settling down and find he would rather sit and watch it than go to sleep 😂
