Oh dear sorry to hear that Azz, I was asked that very same question what if they both had downs. My reply was if it was only one baby, I'd still have it no matter. But when you have twins plus an older child to consider, it's a gut wrenching decision, and I really hope it's a decision that you will NOT have to make. I'm keeping everything crossed for you, you must be going through hell at the moment. I think it's probably best to try and stay positive it may all come to nothing. My friend was told that she had a 95% chance that her baby was going to be downs, he turned out perfectly fine. He is now a thriving 5 year old, so a lot of these tests do turn out to be nothing at all. Thinking of you Azz and make sure you come back and let us know how things are going.
