If your baby only sleeps when held, there are a few things you can do to help them (and you!) get some rest. First, make sure that they are getting enough food during the day. A full tummy will help them feel sleepy at night. Second, establish a bedtime routine including a bath, story time, and cuddles. This will help signal to your baby that it is time to sleep. Finally, try giving them some space to fall asleep on their own. Put them in their crib or bassinet awake but drowsy and let them drift off to sleep on their own. If they cry, try soothing them with your voice or a pacifier without picking them up.
