The time has come
Everything is ready: The baby is preparing to take his first breath and he lies still in his protected environment because now there really is no more space to move around. The bag has been packed, parents wait in anticipation for things to get going, and do a final check of the nursery to reaffirm that everything is ready for your new arrival.
It should be noted that hardly any baby is born on the calculated delivery date. Nature does not do fixed birth dates ...
