You will need to inform the local VO, and add the new baby to the application. It's not a problem but it may take some more time to process your application.
It's actually more of a problem if your wife is pregnant and has the baby between visa issuance and landing. Because the baby will not have a visa. So try to time either your blast-off or your landing...
