Get Rid of Sleep Associations
The key to self-soothing is getting rid of any sleep associations your baby may have. A sleep association can be a routine or object that they rely on in order to fall asleep. It may be rocking or feeding your baby until they fall asleep, or it could be a specific stuffed animal or pacifier that they always need with them.
While there is nothing wrong with these things in themselves, it can create a problem for your baby’s sleep in the long run. When they wake in the middle of the night, they may become easily distressed when they find that their pacifier has fallen out and they can’t find it. Or they may be waiting for you to come and rock or feed them again so they can go back to sleep.
