Use an app called 'Baby Tracker' to track feedings/poops/pees for the first few months. We stopped using it about 5 months in but it was really useful early on when you're "supposed" to watch those things closely. Both mom and dad can have the same profile set up so you can both input entries from separate phones and it will update on both.
Also i would recommend changing diapers as much as you can. The facetime early on will really help build a relationship with your baby.
