I just use one off Amazon has so many different sounds and a light feature if needed you can have it go all night or set it on a timer, you don’t need to spend loads on a sound machine as they all basically do the same thing, hope this helps x
I have the Nanit sound and night light. Can control to from your phone and has a ton of different colors and sounds.
I use hatch but honestly I don’t think it’s worth it we only use one sound and the red light on it and I could find that with a cheaper one
We use the portable lumi one and it’s amazing. Lots of different sound options and different light options too. Great for night feeds.
i use the tommy tippie dream maker it has a red light that mimicked breathing and if on the timer setting turns itself back on when it senses baby cry we personally leave it on all night and for all his naps truly has changed his sleep for the better
My son uses the Lumi one and it’s amazing x
