Please note: This is a companion version & not the original book. Sample Book Insights: #1 The baby's circadian clock, which is insensitive to red light, is highly sensitive to the blue light that is a component of regular white light. I bought a red light bulb for the nursery, and used it exclusively during night feeds and diaper changes. #2 Newborns wake up every two to three hours to feed, and to establish a good milk supply. You must feed a newborn frequently to ensure weight gain and a good milk supply. But you can help your baby sleep better by establishing light habits from birth. #3 The light in a baby's room should be blocked out completely to avoid waking them up too early. Get blackout shades for the sleep area and the diaper changing area. #4 The light in baby's room should be dark until it's time for baby to wake up, at which point it should be light enough to help baby wake up. The light in the evening should be red, as it will suppress melatonin production and help baby sleep.
