Bub has been using white noise to go to sleep. But I’ve found being out and about I’ve had to use my phone which isn’t ideal and I don’t really want it near bubs head. I heard abt these riff raff toys. They play white noise (suppose to mimic inside mums tum). It goes everywhere with us and made made sleep times SO much easier. Just wanted to share my great find!
