The HoMedics myBaby Soundspa On-the-Go is a must-have for busy new moms. It plays four different soothing sounds, including Heartbeat, White Noise, Ocean, and Lullaby, and has an adjustable volume control so you can get the sound just right. The adjustable clip attaches to strollers, diaper bags, car seats, and more, and it’s small and lightweight enough to slip into a purse. The auto-off timer can be set to 15, 30, or 45 minutes, making it perfect for naptime!
