Sudden Unexplained Infant Death

This is a multicenter genetic study aimed at identifying new genes/variants associated with sudden infant death syndrome (SIDS) based on whole-genome sequencing of family trios

The goals of this observational study is to assess whether a new advanced wireless skin sensor vital sign monitoring system can effectively monitor the vital signs of healthy newborn infants (≥ 35 weeks gestational age). The main aims of this Study are to: 1. Assess feasibility 2. Evaluate safety 3. Determine accuracy of the wireless monitoring system, compared to the standard of care wired vital sign monitoring system, immediately after delivery and for the first 2h of age in the obstetrical center under unsupervised parents' care. The newborn infants participating in the Study will have both vital sign monitoring systems placed on their chest and limb. Their vital signs will be monitored for 2h consecutively.

The study team will evaluate the impact of an Infant Sleep Assessment (ISA) tool with motivational interviewing (MI) communication training on clinician-parent communication during 2-month Well Baby Visits (WBV) and parent reported and observed infant sleep practices. The study team's hypotheses are that 1) clinicians who utilize the ISA with MI training will more effectively communicate safe sleep information to their patients' parents, and 2) these parents will have safer infant sleep practices than parents whose clinicians are in a standard of care control group.
