I used a sound machine for all my boys starting from birth, but Oliver is the only one we purchased the Hatch Baby Sound Machine for. Fast forward 5 months and we use this machine for all naps and throughout the whole night, I must say nothing compares to the user friendly, soothing sounds, and complete personalization this product has to offer. I'm a huge advocate for using white noise to soothe from birth, Both Liam and Finn loved their white noise and use it in their room
