Breastfeeding is far superior, because as the husband there's nothing I can do to help the kid in the middle of the night.
Make sure your stroller can hold an incredible amount of bags. It's insane what you have to take with you when you leave the house.
Superstore is very good for diapers.
Probably sounds bad, but we had a cage for when the kid can move around, but you have to get things done around the house. Basically it's just a foldable plastic wall that makes 4-8 walls. We found it much more useful than a pack-and-play or whatever else you would put in the living room to keep the kid in, because you can fold it up in seconds and only pull it out when you need it.
