Munchkin is at it again, I had purchased the Munchkin Music Box with different sounds of Heartbeat, Ocean(waves and seagulls, White (sounds like the Amazon) Mozart, Rain(rainstorm) and 6 different Lullabyes; has Volume control turn nob; timer 15-60 minutes; Projector screen system with 3 different slide screens for all Sounds; it has a built in Nightlight automatically on. I absolutely love this system, for the first couple months I used the Heartbeat and it actually sounds like a Heartbeat not scary Thunder. I love this and has not affected my Hydro bill. My Daughter loves the Lullabyes to sleep to. very efficient and cheap for what it is. I have purchased it for a few babyshowers I have attended to; it is super handy. cute little box with so many nursery bedtime essensials to help baby sleep. I hope you enjoy as much as my family!
