Uh...excuse my ignorance, but do you think what one says to an unborn baby affects physiology?

My wife will be give birth at next end of the month.
How to say to baby to ask him stay in mummy tummy until the exact day to come to this world?
"Baby, please stay until the exact give birth day?"
'Please don't come early, baby'.
This is one of the way bonding with unborn baby and baby can feel it too.
As it turns out, you're way ahead of the curve as far as getting a jump start on your newborn's learning, because a new study shows that babies hear and learn from their mother's voice in utero.
"Don't come until you're due."
What you call "the exact give birth day" is called the "due date for delivery". You can ask a pregnant woman "When are you due?" or "When is the baby due?"
Please be born on the due date.
