One of the most frustrating situations that parents may face is figuring out how to get an overtired baby to sleep. Exhausted or overtired babies fuss and cry, preventing them from relaxing their bodies. When an overtired baby finally goes to sleep, she is likely to wake up sooner than normal, finding it even harder to sleep again. This may make you feel confused as to what exactly you should do to help your little one relax and fall back to sleep.
