After much debate, we have decided that DS will be our one and only.
It was a hard decision, but we know it is the responsible thing to do. We have a very high chance (60%) of having another child with the same condition as DS. Not only would that be hard in and of itself, it is also a huge financial burden that we wouldn't be able to handle well.
I am grieving right now for sure though. For the large family we will never have that I always really wanted, for never being able to breastfeed (DS couldn't) etc.
Hopefully in a few days I will be able to focus on all the good things we will be able to do now that we wouldn't have been able to do otherwise.
