Night-time settling
This article has a good summary of the things you can try to help a new puppy relax at bedtime. Remember, it is fine for you to stroke or reassure them or stay near them at first and gradually wean them off your presence as they fall asleep - it is a big transition to leave their mother and siblings and suddenly be all alone in a laundry. Post any questions or problems below if these basics don't help or you're not sure about your overnight set up, or head to the Facebook group if you need to show me any videos.
