Ultrasound

I am almost 18 weeks pregnant. Next week I will have an ultrasound to make sure everything is ok. I have one daughter who is Autistic and one niece who has Downs Syndrome. Even if there is something wrong we will still love this baby just as much as we do Alli and Gracie. Knowing ahead of time won't change anything. My husband and I are trying to decide if we want to know what the sex of the baby is. On one had it would be nice to be prepared and have everything ready, but on the other I like the surprise at the end just like I did with my other three children. If we do find out the sex we still may keep it a secret from everyone because they already know what name we have picked out. Oh boy would it be hard to keep that secret.
