Multiple pregnancy delivered on different dates

Multiple pregnancy delivered on different dates

We have had a number of incidents reccently where multiple pregnancies are having babies delivered on different dates. this makes things very difficult as we cannot enter all of the delivery information to get NHS numbers as we have to leave the lady 'pregnant@ so we can still carry on caring for her as an AN woman also with the second/third baby? can we have something in Guardian to enable this scenario to run smoothly?
