Soul entry in baby's body!

And its bodily functions also continue to maintain the body since it is formed, and other functions are also get added one by one. With the perfect coordination and functioning of all the fully developed organs, a 'bodily Soul' is formed/enters inside the baby's body either before or after its birth! At which time of being inside mother's womb (or at which time after its birth out of it's mother's womb) is this Soul (the motor part of Analytical mind)  formed in (or does it enter) the baby's body?
