don't throw the baby out with the bath water origin
Don't throw the baby out with the bathwater Some claim the phrase originates from a time when the whole household shared the same bath water.[9] The head of household (Lord) would bathe first, followed by the men, then the Lady and the women, then the children, followed lastly by the baby. The water would be so black from dirt that a baby could be accidentally "tossed out with the bathwater".[9] Others state there is no historical evidence that there is any connection with the practice of several family members using the same bath water, the baby being bathed last.[10]
Amniotic fluid Swallowed amniotic fluid creates urine and contributes to the formation of meconium. Amniotic fluid protects the developing baby by cushioning against blows to the mother's abdomen, allowing for easier fetal movement and promoting muscular/skeletal development. Amniotic fluid swallowed by the fetus helps in the formation of the gastrointestinal tract. Contrary to popular belief, amniotic fluid has not been conclusively shown to be inhaled and exhaled by the fetus. In fact, studies from the 1970s show that in a healthy fetus, there is no inward flow of amniotic fluid into the airway.[4] Instead, lung development occurs as a result of the production of fetal lung fluid which expands the lungs. It also prevents the fetus from mechanical jerks and shocks.
