This is a long-term observational study that follows pregnant women and their children over several years. Researchers want to understand how the bacteria living in a mother's gut during pregnancy and after birth influence her baby's immune system development, risk of obesity, and brain development. You would participate by providing blood and stool samples at various points, along with information about your pregnancy and your child's early life.
Doctors and scientists know that the bacteria in our guts play an important role in health, but they don't fully understand how a mother's gut bacteria 'talk to' her developing baby, or how this early microbial exposure shapes lifelong health outcomes like allergies, obesity, and developmental delays. This study aims to fill that gap.

You would visit the medical center during your pregnancy and then regularly after your baby is born for at least 3 years. At these visits, you would provide blood and stool samples, and answer questions about your health, diet, pregnancy, and your child's development. The study is observational, meaning researchers are watching and collecting information rather than giving you any new medication or treatment.
