My kids have been mesmerized by the gentle motion of the wave maker for hours now, and the sound it creates is surprisingly calming. It’s so simple to use but sparks their imagination every time they pick it up.

My 4-year-old figured out how to make gentle waves in about two minutes, and now we take turns before bed. The sound it makes really does capture that calm ocean feeling, and the simple wooden construction feels nice in your hands.

I've been using this to fall asleep, and the wave sounds are genuinely soothing—not tinny at all. It's a bit pricey for what it is, but it does exactly what it promises.
