We are currently enrolling children with Down syndrome between the ages of 10-20 years. This study is aiming to compare at home sleep studies and in lab sleep studies; participants will be asked to complete both kinds of sleep studies and give their feedback on the experiences.

This study seeks to understand why some babies born with a small jaw (micrognathia) have sleep apnea and/or trouble growing and others do not. By enrolling healthy babies, we hope to get a better understanding of how infants breathe during sleep and grow over the first months of life. This observational study involves two study visits that each include an overnight sleep study and some other non-invasive tests.
