Do everything in 2's. Everyone eats at the same time, gets dressed at the same time, naps/sleeps at the same time, etc. Otherwise they would double team me and drive me crazy!
Of course, this works better as they get older

Newborns aren't going to automatically be on older sibling's schedule...but as they get older I work like heck to make it work that way, if only for my own sanity!
