Thanks Kazzo

Thanks Nickle730- I think for me it's fear of the unknown. All the scans with DS were fine. We didn't know there was any problem until we took him to hospital at 9 days with what we thought was a cold. He was in heart failure. I'm trying so hard to enjoy this pregnancy as much as I enjoyed my other two but it's so hard to block out the fear. It's not just me either but I don't want my DD to go through it again. She was only 17 months when her brother was born and she pretty much lost her parents for 9 weeks as we were sitting by his bedside in hospital.
I know what you mean about having another sibling for your eldest just in case. We always wanted three but it seemed even more important with DS's health that we have another sibling for DD. It's awfully morbid but I'd hate her to be left alone.
