If this was her first child I would be worried. But being her third an OB nurse along would be more than sufficient.
Many of these trained ladies do more than the doctors when it comes to the actual delivery process
Good point about the OB nurses. She and her husband make such a lovely couple I just hope and pray everything goes OK for them with this child. OK - so call me a worry wart and being overly protective, especially when it comes to kids and babies and their moms.
