would you want them as your first and second...
or as your second & third (or subsequent) children?
My brother and SIL are in town and they joked about having twins and getting all their children out at one time... they asked if I would've wanted twins at all.
In hindsight, I would have wanted twins as a ftm just because becoming parents is a shock to your system anyway! But then they asked if having twins later on (after having a singleton) would be easier since you're more confident as a parent!
What would you prefer! (as if you can choose :P)
