As someone who works with infants and as an adult who needs white noise to sleep, I can't recommend the Hatch sound machine enough. I ALWAYS recommend white noise to my clients for the baby's room and this is why I recommend the Hatch machine. It can be programmed and adjusted through your phone so you don't disrupt baby, it grows with your child so you can adjust according to your child's needs as they grow, it has a toddler lock, stays cool through the night, and it has different color combinations and sounds that are recommended by sleep experts. This truly is an all in one machine.
