How long does it take for a newborn to detox in your stomach while still pregnant?

During pregnancy, a newborn does not detox in the mother's stomach; instead, the fetus relies on the placenta for nutrient exchange and waste removal. The placenta filters some substances, but it doesn't completely eliminate toxins. Any detoxification process, if needed, would typically occur after birth. It's essential for pregnant individuals to maintain a healthy lifestyle to minimize toxin exposure for the developing fetus.
