No one would guess that they are twins (different kindy classes) or that they were prem.
I've recently lost another twin pregnancy. One twin didn't develop properly due to blood flow and we also lost his identical twin brother at 19w.
Both my twin pregnancies have been quite difficult and there have been a few major problems along the way. From my experience if you can get them to a healthy gestation then they tend to be fine.
This website helped me keep focused while on bed rest:
