Yes I still breastfed two at once. They are 11 months old and we are weaning now. I do the under arm football hold! Its one if the things that is a little less nice because you don't get the snuggle hold with one. Some people feed separately but its easiest in my opinion to do it once, not spend double the time. I never breastfeed in public! Ha! That would just be too much! So sometimes I'm on side roads out of town in my car trying to be discreet!
As for sleeping...on the same routine. In the early days when one woke, we woke the other for a feed. They slept together which was one of the benefits of twins, we never had a sleepless night. They provided so much comfort for one another. Now they are in separate cots but cots are right beside each other touching.
Having said all this, it is certainly not the case for all twins. Mine are identical and born the same size so I've had no problem keeping them together on eating, sleeping etc. Often this is impossible with different needs.
