Thankyou for all your replies!

I was shocked that she was told to feed 4 hourly!

I will be ringing her today to see how she is going, her DD is in CC 3 days a week, so she has a bit of a break.
I didnt even ask why she was using the shield will find out today.
I know she was expressing a bit in the hospital, I am going to lend her my pump so she can continue to pump if she wants, might help to up the supply in the other boob.
Thanks again ladies, youre all fantastic!
