Isobel is poorly

I have just had a call from the hospital from Mary one if the nurses to say Isobel has not had a good night. She seems to be telling me it is a dip and that it isn't too bad; but it is still terrifying. I wish the babies were all closer.
I am so worried.
I called the hospital back because I didn't take in really what they said. But they are removing her long line. I now have no idea if that is a good thing or a bad thing.
