Wonder Weeks, also referred to as leap weeks, are weeks in which your little one experiences a sudden new development in their skills and understanding of the world around them. They were first detailed in a wonder weeks book released in 1992, and are now popular worldwide as a way of measuring your baby's growth.
There are ten leaps in total, and eight of these are experienced before your baby reaches their first birthday. However, in addition to bringing new skills, they can also have an effect on your baby's mood, leading to fussiness that can negatively impact their sleep. To counteract this, you can use tools like sleep training, a regular schedule, and a soothing bedtime routine with our gently weighted Zen Sleepwear.
