If you have multiple floors in your house set up somewhere to have diapers and change the baby on both floors. Especially for the first few months.

Start sleep training and establishing a schedule early, in the second or third week. It will help immensely as the schedule solidifies. Also make sure you let your baby go to sleep by themselves at least occasionally.

The overlap between training pets and babies is significant. The same is true with toys for kids and pets. I’m not saying buy dog toys for your kid, but be prepared that any laying around may become the most interesting thing in the world.
