Did your babies wake each other up?

How did you keep them on a schedule?

What about growth spurts when they get hungry/sleepy at random times?

What about when one was ready to give you 5-6 hour stretches but the other would not sleep beyond 3.5 hours? Did you still wake up both together?

Basically how does this ‘keep on a schedule work?’

Or is it only for twins who are in fact close together in sleep/feed/geowth?

Thank you.
