What are Wake Windows?
A "wake window" is the amount of time your baby can stay awake comfortably between naps. If you keep them awake too long, they become overtired and fight sleep! Use this calculator every morning to figure out when to put your baby down for their first nap based on the time they woke up.
Set the mood for sleep: Make sure your baby is comfortable during their nap. Shop our ultra-soft, breathable swaddles and nightwear at Sweet Angels for a longer, peaceful sleep.
