Sleep hygiene refers to habits and behaviors that can help you get a good night's sleep. It applies to babies, toddlers, kids, teens, and adults! Good sleep hygiene can improve sleep quality, reduce your risk of developing sleep disorders, and improve your overall well-being. Some sleep hygiene tips for the hazy newborn days include: create a relaxing bedtime routine for yourself, not just your little one, keep your bedroom dark and cool to promote the production of the sleepy hormone melatonin, and avoid caffeine and alcohol before bed.
