Welcome to Mind The Kids, hosted by Mark Tebbs. In this episode, Mark sits down with Dr. Charlotte Viktorsson, a behavioural genetics researcher at Uppsala University, to explore the genetic and environmental influences on infant sleep and crying. Drawing on findings from a major study involving nearly 1,000 sets of Swedish twins, they discuss how much of a baby's crying is down to genetics and why sleep quality often depends on home routines and environment.

If you're a parent in the thick of sleepless nights or frequent tears, this episode offers both reassurance and fresh insight. Dr. Viktorsson explains why some babies simply cry more than others—even in the best of circumstances—and shares practical advice for supporting your child's wellbeing in those challenging early months. Tune in for an enlightening conversation that brings clarity and comfort to anyone caring for young children.
