Not necessarily a whiteboard, but a schedule yes. People tend to use apps to track the baby's rhytm at first, so they can make a schedule that fits with the baby's needs (which are most likely different then your own). Having a schedule makes things more predictable for the baby as well, so there is less fuss. We have done it with all our children and it has worked like a charm. Using apps like Huckeberry to log eating, sleeping etc. is really helpful. Not only do you know if they are eating and sleeping enough, but when you go to visit the hospital/doctor for check-ups on the baby you have a greater overview. These things are quite hard to remember when you're in a foggy sleep deprived state.
