A sleep consultant will go over with you the sleep challenges you're facing. They may ask what your current schedule is, how you are responding to wakings, if there are any growths or other medical concerns. They will then explore solutions with you.
They may advise changes to your current schedule, outline options for coaching your child to sleep and explore ways to create a positive sleep environment. They may also refer you to a medical professional if they see any issues that they feel may need further exploration. They will also offer suggestions to try to improve sleep for your child.
