HAPPY BABY, HAPPY PARENTS Our Sleepy Baby Biological LED Nursery Lamp creates the perception of darkness for your infant's internal clock, while providing the perfect light output so you can care for your little one. The proprietary LED spectrum works with your baby's natural circadian rhythm to help them fall asleep faster, stay asleep longer and fall back asleep quicker if awoken in the middle of the night. Plus, it supports your baby's natural melatonin production- a hormone needed to regulate their internal clock and help them develop a healthy sleep cycle.
