Are two harder than one?

I've had many people ask me if twins are a lot harder than singletons.  I don't know for certain.  I never had any other children.  For me, babyhood wasn't hard.  You do one simple task (feed, bathe, diaper) and then do it again.  We had the boys on identical schedules so everything was at the same time.  They even cut their teeth on the same days.

We worked out lots of ways to feed two at once from two high chairs reclined back to back, to fast spoon feeding side to side, to holding/feeding one in a chair at the mall and rocking the stroller with my foot!

I could carry both of them for quite a while and my arms got strong.  They always liked to sit in my lap at the same time - one on each leg.  They still do that once in a while but you can't see me over them.  They weigh about 100 lb each.

I can say that one of them is many times easier (should that be a fraction?) than both of them.  It also is a time to really hear the individual personality come out.  They are very much alike; but have differences in how they view some situations, some likes/dislikes, humor, and such.  Their taste in color and clothes though, is almost identical.  Once I let each independently pick out 5 t-shirts online.  They picked the same colors.

As nearly eight year olds, two are clearly more challenging than either one of them, but I doubt they are harder than two siblings of different ages.  They might be easier because they are in the same grade, lifestage, etc.  I think many young woment fantasize about having twins.  I say "Go for it!"
