DO A BABY AND MOTHERS BLOOD MIX?

Yes, a baby and the mother's blood can mix during pregnancy, but they typically remain separate within the placenta. The placenta acts as a barrier, allowing the exchange of nutrients and waste while keeping the mother's and baby's blood systems distinct. However, small amounts of fetal blood can enter the mother's circulation, particularly during labor or if there's any trauma to the placenta. This is why blood type compatibility is monitored during pregnancy.
