Babies' Teeth Could Reveal Truth About Moms' Stress Levels
Summary
A study by researchers at the University of Rochester found a link between a mother's stress during pregnancy and the early development of her baby's teeth. High levels of the stress hormone cortisol in mothers were associated with babies having more teeth by six months of age. The research indicates that prenatal stress might affect the child's growth and development in significant ways.Key Facts
- The study was conducted by researchers from the University of Rochester in New York.
- Mothers with high cortisol levels during late pregnancy had babies who grew teeth earlier than usual.
